The Water Conservation Capacity of the Ecotone of the Forest and Grassland in HulunBuir

Abstract:

Based on the remote sensing data and meteorological data of MODIS, this paper studied the water conservation capacity of different land use type of the ecotone of the forest and grassland in Hulun Buir with the help of the ArcGIS software. The results shows that the average of the water conservation capacity of 11 years of the whole ecotone of the forest and grassland in Hulun Buir is 62.78×108m³/yr. Among of these, the forest land accounts for 69.37% of the total water conservation capacity, and the grassland, the cultivated land and the unused land account for 23.36%, 3.67% and 3.60%. And the water conservation capacity of the four land use types presented a fluctuated improving trend. The average water conservation capacity in each year of the unit area of the ecotone achieved its maximum value, 498.43m³/hm² ,in 2003, and achieved its minimum value,193.03m³/ hm²,in the year of 2007.
