- Abstract:
-
The effect of Grain for Green Project on ecosystem service was evaluated by the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model in the Dali River Basin. The land use/land cover data of 1980, 1990, 1995, 2000, 2005 and 2010 years were used to calculate the ecosystem services of carbon storage, soil conservation and water conservation. Under the Grain for Green Project, ecosystem services mainly increased in the basin. The main conclusions were as follows. (1) In the past 30 years, the land use/land cover of the study area changed significantly, that forest and urban areas increased by 31.52 km2 and 0.65 km2, respectively, while the areas of farmland, grassland and water body decreased by 2.49 km2, 27.32 km2 and 2.36 km2, respectively. (2) Carbon storage volume had steadily increased in the 30 years. Forestland had the most significant carbon sequestration, followed by grassland, and the farmland. (3) Soil conservation mainly increased in the basin. The soil conservation capacity of farmland was obviously lower than those of woodland and grassland. (4) Water conservation little decreased in the study area in the past few decades. The water conservation not only depended on the land use/land cover, but also the annual rainfall. This study evaluates the effect Grain for Green Project on ecosystem service of Dali River Basin, which can provide scientific reference for future ecological planning.
