- Abstract:
-
Based on the remote sensing data of Yuli County in 1993, 2001, 2009 and 2017, the values of ecosystem services were amended by using the method of estimating the service value of land ecosystem in China and combining the actual situation of the study area. The change of ecosystem service value caused by the land use/cover change of Yuli County was analyzed. The results showed that in the period from 1993 to 2017, the total area of different land use types in Yuli County presented the ‘six increase and three decrease’ pattern, i.e., cultivated land, construction land, water area, wetland, salinized land and desert area had increased, the areas of woodland, grassland and unused land had decreased, and the total value of land use ecosystem services in Yuli county rose. The value increased from 17.361 billion yuan in 1993 to 20.63 billion yuan in 2017, the net increase was 3.269 billion yuan. During the whole study period, the contribution of the land use types to the total value of the ecosystem services decreased in the order:wetland > grassland > desert > water body > woodland > cultivated land > salinized land > construction land; sensitivity analysis showed that the sensitivity index of each land use type was less than 1, which shows that the value of ecosystem services provided by land types has little influence on the total value of ecosystem services, lack of elasticity, and the results are credible.
