- Abstract:
- We took Huanghua city as the study area, used the ENVI remote sensing to interpret out 1990, 2000, 2014 three period images of Huanghua City, analyzed variation characteristics of various ecological types, used the ecosystem service value evaluation method to calculate the ecosystem service value of the region and analyze its changes. The results showed that: (1) from 1990 to 2014, garden and construction land areas increased, cultivated land, grassland, water, saline alkali land and unused land areas decreased in Huanghua City; (2) the land ecosystem service values in 1990, 2000 and 2014 of Huanghua City respective were 4 186.294 7 million Yuan, 4 150.556 8 million Yuan and 4 113.720 7 million Yuan, respectively, the land ecosystem service value totally reduced 72.574 0 million Yuan, Among them, the ecosystem service values of garden and construction land increased, the ecosystem service values of cultivated land, grassland, water, saline alkali land and unused land decreased; (3) from 1990 to 2014, contribution of water conservation and waste disposal service function value to land ecosystem service value structure was the largest, the raw material was the least. In addition, only raw material supply increased, the others decreased, and waste disposal reduced the most in the study area.
