- Abstract:
- Land use types were classified through the combination of computer automatic classification and manual interpretation based on the Landsat TM images acquired in 1991,2001,and 2006.Information of land use types was acquired and then ecological service value was estimated.The results showed that the land use in Changshu changed considerably during the period from 1991 to 2006.Town and construction land increased intensively,wetland and forest increased a little,while crop land decreased evidently.The ecological service value declined a little.During the period of 2001 and 2006,the town and construction land was further expanded,wetland area increased notably,while crop land and forest decreased a lot.Analyzing the effects of land use change on ecological service value can provide support for scientific and reasonable land use,keep the balance of ecosystem,as well as the sustainable development of population,resources and environment while making decisions.Coefficient of sensitivity analysis showed that the ecological service value was not sensitive to the change of ecological service value coefficient.So the result was credible.
