- Abstract:
-
Evaluation of ecosystem services values of landscape pattern is helpful for people to understand the importance of the natural ecosystem in terms of human welfare. Based on the interpretation of remote sensing data in 1996 and 2015 as well as settlements data of Lanping County, wer analyzed the influence of human activities on landscape pattern change and ecosystem service values by ArcGIS technology and ecological value evaluation method. The results showed that:with the development of social economy and relevant policy, land landscape patterns of forestland, cultivated land and construction had changed greatly; according to the 443 settlements and the basic data of different climate zones, human activities mainly concentrated in the temperate range with the elevation of 1 900~3 000 m; human activities had the important impact on the change of landscape patterns of land uses; the total value of ecosystem service in Lanping County increased by 440.351 9 million yuan within the 20 years, among which the contribution rate of service value of different ecological service functions decreased in the order:soil formation and conservation, gas regulation, water conservation, biodiversity conservation, climate regulation, raw material, waste disposal, recreational culture, food production; the total value of ecosystem service of different land use landscape decreased in the sequence:woodland > cultivated land > water > grass > construction land > unused land.
