natural condition

topographic features

The forest farm belongs to the type of low mountain and hilly landform, with the main vein of Dagui mountain as the center, extending to the northeast and southwest respectively, and the two branches of the main vein extending to the southeast and northwest respectively, and gradually falling into low mountains, transiting to Xindu basin in the South and Liantang basin in the north. Due to the huge mountains and towering peaks, Dagui mountain is the natural barrier of Xindu and Liantang basins. The altitude in the forest farm is generally 200-600m, with the highest altitude of Dagui mountain 1204m and the lowest altitude of 80m. The topography of off-site afforestation includes middle mountain, low mountain and hill. Because each county (city, district) is located in a different area, the landform type, topography and topography are different. However, most of the forestation land belongs to low mountains and hills, and the altitude is below 800m.

climate

The forest farm is located in the north of the Tropic of cancer, in the transition zone between the middle and south subtropics. It is a humid subtropical monsoon climate in China, with abundant heat and rainfall, which is suitable for the development of forestry production. The annual average temperature is 19.3 ℃, the extreme maximum temperature is 39.7 ℃, the extreme minimum temperature is - 2.4 ℃, the annual accumulated temperature is 6243 ℃, the annual average rainfall is 2056 mm, the annual evaporation is 1275 mm, the average relative humidity is 82%, and the frost period is 12 days. The superior rain and heat conditions are very favorable for the growth of trees. The off-site afforestation is located in two climatic regions of south subtropical and middle subtropical. The annual average temperature is 19-21 ℃; the annual average active accumulated temperature is 5000-7000 ℃; the annual sunshine hours are 1600-1800h, the precipitation is 1200-1700mm, the evaporation is 1300-1500mm, the average relative humidity is about 80%, the frost free period is more than 305d, and the climate conditions are suitable for forest growth.

soil

The parent rock of forest land is mainly Cambrian sandstone and sand shale, followed by Yanshanian purple sandstone and sand shale, and a small amount of granite and other parent materials. The soil is mainly mountain red soil, followed by purple soil and mountain yellow soil. The purple soil is mainly distributed near Liupai branch yard and Dadong Station of Dongye branch yard and Renyi branch yard. The soil texture of the whole site is mainly clay loam and loam, and the pH value is 5.0-5.5; the thickness of the soil layer is mainly medium and thick (≥ 40cm), the humus layer is generally less than 5cm, and the soil fertility is low. The main soil types of off-site afforestation are red soil, yellow soil, lime soil, purple soil and alluvial soil. Most of the counties (cities, districts) are located in the red soil distribution area. The soil layer of the forestry land is medium thick, more than 60 cm, and the soil fertility is medium.
