- Abstract:
-
Assessment of ecosystem service has become an international hot point of ecology and economics. Water regulation is one of the important services of grassland ecosystem. It is the comprehensive performance of interactions among vegetation, water and soil. We used the rainfall storage capacity method to calculate the water regulation amount of grassland ecosystem in different regions and periods in China based on the grassland vegetation coverage, and evaluated the spatiotemporal dynamics of water regulation service for grassland ecosystem. The following conclusions were obtained. Compared with the first ten years (1980s—2000), the annual mean water regulation amount of grassland ecosystem in China increased by 2.215 billion m3 per year during the period from 2000 to 2010. At the same time, the water regulation service ratio of grassland ecosystem increased by 4.80%. The water regulation service of grassland ecosystem in China was somewhat improved.
