生態(tài)輸水前后塔里木河干流生態(tài)系統(tǒng)服務價值的變化過程
[Abstract]:The changes of ecosystem service value during the process of ecosystem degradation and the change of ecological service value during ecological restoration after water transfer in the main stream of Tarim River were analyzed. Based on RS/GIS technology, three Landsat TM/ETM remote sensing images of 1990 and 2010 were used to extract land use / cover type information, and to calculate the value of ecological services. The results showed that the ecosystem service value of the land use type in Tarim River decreased by 1.143 billion yuan and 8.5 yuan from 1990 to 2000, and decreased at the rate of 114 million yuan per year, mainly due to the natural forest land, irrigation and grassland. The area of wetlands and inland water bodies has been greatly reduced, resulting in the continuous loss of the value of natural capital in the area; during the ecological water conveyance period of the Tarim River (2000-2010), the value of ecosystem services increased by 1.257 billion yuan, an increase of 10.21 yuan, and an increase of 126 million yuan per year. This is mainly due to the increase of inland water area caused by ecological water conveyance project which began in 2000. Conclusion: before ecological water transfer, the value of ecological service in the main stream of Tahe River decreased generally, and the value of ecological service showed an upward trend during the process of ecological water transfer.
