Valuate of Soil Conservation of Grassland Ecosystem with GIS and Remote Sensing Technology

Article Preview

In this study, we use d remote sensing and GIS technology to estimate the value of soil conservation. The Revised Universal Soil Loss Equation (RUSLE) was used to estimate soil erosion quantity. The total amount of soil conservation of grassland ecosystem was 79.25×105t/a in HulunBuir in 2006, the total value was 81.58×107yuan/a, in which the economic value of soil fertility conservation, reducing abandoned farmland and reducing silt accumulation were 80.39×107yuan/a, 0.694×107yuan/a and 0.50×107yuan/a respectively. For the different grassland types, lowland meadow was maximum, next was temperate meadow-steppe. Marsh was the minimum.
