Moon Lake

Dengyue lake, formerly known as yazuiqiao reservoir, is located in Yuetang Town, Yizheng City, Jiangsu Province. Due to the pure water, green trees and beautiful natural scenery of the lake, it was renamed "Moon Lake" in 1999 to deploy tourism development. Dengyue Lake scenic spot is composed of three parts: Water Park, island sightseeing tea garden (including Yinyue Village) and Yuhuashi sightseeing area. The scenic area covers an area of more than 6000 mu. The water quality is the second-class standard. The ecological environment is excellent, the aquatic products are rich, and there are many wild birds. It has become a good place for tourists to go for leisure and tourism.

Introduction

Dengyue lake is located in the northwest of Yizheng City, only 20 kilometers away from the urban area, with a total area of 32 square kilometers, involving Yuetang and Xieji towns. Dengyue lake is the largest artificial lake in Central Jiangsu Province. In recent years, eco-agricultural tourism has been vigorously developed. Since 2002, the tourist flow has increased greatly.

In 2003, the tourism industry in Zhejiang Province, with the Grand Canyon in the west of Zhejiang Province as the main body, established Yuetang tourism development company to participate in the tourism development of Dengyue lake. With brand-new business philosophy and rich practical experience, they have rebuilt the moon lake. Now they have invested 10000 yuan to implement the planning and construction of three scenic spots, namely leshuiwan, Moon Island and Bailongshan. They have launched a new tourism mode of "three points and one circle", combining water and land, and combining dynamic and static. Leshuiwan and Bailongshan, two scenic spots, have been officially opened in October to receive tourists.

In the beautiful plain of Central Jiangsu, Dengyue lake is praised by the world for its pure water quality. Yuetang tourism development company, with the Grand Canyon in Western Zhejiang as the main investor, has re intervened in the tourism development of Dengyue lake. In the first phase, it has invested 15 million yuan to open up three tourist spots, namely leshuiwan, Dengyue island and Longshan treasure exploration area, on the 16 km lakeshore belt around the lake. The "three spots and one circle" tourism mode is used for tourists from all over the world to come here for sightseeing, sightseeing and leisure. The main tourism projects include:

Leshuiwan: scene modeling of ten wisdom stories

Landing on the Moon Island -- a happy island with land and water, dynamic and static

Longshan treasure exploration area: simulating Yuhuashi mine and exploring gems

Water recreation - water slide, water swing, boat, yacht, water bicycle, etc

Main attractions

Leshuiwan

Leshuiwan covers an area of 200 mu with various recreational facilities. The name "leshuiwan" comes from an old Chinese saying "benevolent people enjoy mountains, wise people enjoy water", which means that people who like water will become very smart. "Leshuiwan" is the most representative theme tourist area of Dengyue lake at present. With the theme of displaying wisdom and increasing knowledge, "leshuiwan" is divided into six theme amusement blocks: Tangram playground, tianwenyuan, wisdom Story City, Qiqiao square, shuihan slide and cruise ship wharf. The landscape modeling of each block has its own connotation or historical allusions and historical figures. It reflects the profound creativity of the builders.

It is rare to make "Mathematics" into "tourism" in the construction of scenic spots at home and abroad, which can be called a wonderful work of tourism landscape. The specific items are as follows:

A. Jigsaw puzzle

Mathematics origin: Tangram is an ancient toy invented by Chinese, which foreigners call "tangtu". Seven geometric figures can be pieced together according to different methods to obtain a variety of patterns, which is quite beneficial to the training of children's intelligence. This kind of toy is highly praised all over the world for children's play.

Tourism project: more than ten mu of "Tangram paradise" is set up in leshuiwan scenic area. There are seven geometric models showing the elements of the tangtu puzzle, twelve kinds of vivid patterns made up of tangtu puzzle, and the tangtu labyrinth with the connecting line of the square made up of tangtu puzzle. Tangtu puzzle game is set in tangtu maze. Before entering the maze, tourists can draw a "Tangram". This Tangram is just missing one piece. Tourists must remember this figure, then go through the maze, enter the palace, and choose the piece you remember in a "Tangram material supermarket". The success of tangtu puzzle is rewarded.

B. Jiugongge flower bed

Origin of Mathematics: in ancient China, our ancestors made many achievements in the study of numbers, and "Hetu" and "Luoshu" are examples of such achievements. In the nine numbers of 1, 2, 3, 4, 5, 6, 7, 8, 9, arranged in a certain way, very interesting results will appear. The ancient "River map" expresses this meaning. Later, it evolved into "nine palace grid", that is, draw nine grids, align them with three or three, fill in nine numbers, and the sum of three numbers in each row and column will be 15.

Tourism projects: in the open space under the smart story City, two flower beds are built. One is nine palace Gabriel, with Arabic numerals written on each grid to clearly see the numbers at a glance; the other is imitating the ancient "River map", with bricks representing several points to form different numbers of patterns. Standing on the wall of smart city overlooking the two flower beds, visitors will be interested in a little explanation.

C. Qiqiao square

The origin of Mathematics: the seven bridge problem is a famous mathematical problem in the history of mathematics. It is said that this is a game discovered by foreigners when they are walking. There is a river in the park of the city of Konigsberg. There are islands in the river, and there are seven bridges on the river. People who come to the park for a walk often come to walk on the bridge. Suddenly, someone asks, "who can walk seven bridges at a time and return to the same place without crossing the bridge again?"? Many people went to the bridge, but none of them succeeded. Later, it became a world problem.

Tourism project: in the center of leshuiwan scenic area, a square of nearly 40 mu is developed. In the center of the square, a river and two small islands are dug out according to the theme of "Seven Bridges problem", and seven stone arch bridges are built. Around the seven bridges, the four areas separated by the river and the island are paved with red, yellow, green and gray floors. For tourists to play the bridge game, that is, starting from a place of one color, one-time through seven bridges without repeating the bridge, back to the same color. In order to increase the pleasure of traveling, we have designed an encouraging promise that anyone who can cross the bridge successfully according to this requirement can get a bonus of 1 million yuan from the scenic spot office.

D. Yuhua stone magic grid

Mathematics: Indian mathematician sisaban is the inventor of chess. It is said that after the invention, the king of India wanted to reward him and asked him what reward he wanted? Sisaban said that he would like to put one grain in the first grid, two grains in the second grid, four grains in the third grid, eight grains in the fourth grid, and so on. He would like to put it down according to twice the number of the first grid and fill 64 grids. The king laughed at sisaban's lack of knowledge and asked for a load of wheat. Said sisaban, wait! Let the king count. The king sent someone to calculate it. It turned out that the 64 squares of wheat were so large that there was not enough wheat in the whole world. Mathematically, this is a problem of summation of equal ratio series, which has been handed down from generation to generation due to its strong story.

Tourism project: the theme of Longshan island is Yuhuashi. The location of Dengyue lake is the main production area of Yuhuashi, and exploring Yuhuashi is a highlight to attract foreign tourists. A simulated "Yuhuashi mine" is set up in the scenic spot for tourists to find and pick up Yuhuashi in the "mine". Yuhua stone is a kind of granular colored stone, which can be counted according to its size. On the edge of the mine, a small platform was built, on which three "sisaban checkerboards" were artistically placed, so that tourists could fill the 64 checkerboards with Yuhua stones to see if they could be filled? We call this facility for putting Yuhuashi in the grid "Yuhuashi magic grid".

E. Cao Chong's image in foreign countries

The origin of Mathematics: the wisdom story known to all women and children "Cao Chong calls an elephant" actually means that different objects have the same displacement and weight. In foreign countries, there is a legend that Archimedes called the crown, which is also a story of praising Archimedes' extraordinary intelligence. The king asked Archimedes to tell if the crown made by the craftsman was adulterated? Because the crown was irregular and difficult to measure, Archimedes had nothing to do. It happened that one day when Archimedes was taking a bath in the bathhouse, the water overflowed out of the bathhouse. Archimedes immediately came up with the idea of using the displacement to measure the mass of objects with different specific gravity. This principle is the same as the Chinese story "Cao Chong called elephant", which is also called "foreign Cao Chong called elephant".

Tourism project: there used to be a low-lying area with long-term water accumulation in leshuiwan scenic area. During the tourism development, it was built into a colorful fish pond to raise a large group of colorful fish for people to watch. On the West Bank of the Caiyu pond, the scene of "Cao Chong calling the elephant" is arranged: under the willow trees and beside the clear water pond, there are wooden boats, elephants and stones. Little Cao Chong is leading the elephant to the boat, echoing with it. On the east side of the Caiyu pond wall, he uses the drawing board to make the story comic of "Archimedes calling the crown", which is both illustrated and easy to understand. Tourists can associate the two scenes to think, which is interesting and intelligent.

F. Tian Ji racing

Origin of Mathematics: game theory is a major branch of operational research mathematics, which is widely used in economic management and electronic technology. The most famous case of game theory in China is the story of "Tian Ji horse racing" in the Warring States period. It was recorded in Sima Qian's historical records. It said that the king of Qi and Tian Ji raced, each with three horses, one by one, to see who won more. clever
