摘要:
以苏州市为例，利用1980年、1995年、2000年三期TM遥感影像解译图获取土地利用变化数据。首先，对苏州市1980-1995年和1995-2005年两个时段的土地利用变化特征进行分析。然后，通过定义不同土地利用类型的相对生态服务价值，分别运用区域生态环境质量指数和区域土地利用变化类型生态贡献率，对研究时段内苏州市土地利用变化的生态环境效应以及导致苏州市生态环境质量变化的主导土地利用变化类型进行分析与评价。结果表明，1980-2005年苏州市的生态环境质量不断下降，苏州市的生态环境质量指数从0.4609下降到0.4431，且下降速度越来越快。其中，导致苏州市生态环境质量恶化的主要土地利用变化类型是耕地向城乡建设用地的转变，促进苏州市生态环境质量改善的主要土地利用变化类型是耕地向水域用地的转变。
Abstract:
This paper obtained the data of land use change based on the TM images interpreted in 1980,1995 and 2005 taking Suzhou as a case study.First,this paper analyzed the characteristics of land use change during 1980-1995 and 1995-2005.Then,eco-environmental quality was associated with land use types according to the relative ecological service value of different land use types.The effect of land use change on the eco-environmental quality was measured and quantified by calculating the regional eco-environmental indices.The major land use transformation types causing the change of eco-environmental quality were found out by calculating the contribution proportions of land use transformation types to eco-environmental quality.The regional eco-environmental quality index decreased from 0.4609 to 0.4431 in Suzhou from 1980 to 2005,which reflected that the eco-environmental quality was continually decreasing; and the rate was faster and faster.In the study phases,the transformation from arable land to constructive land was the major land use transformation type deteriorating the eco-environmental quality; the transformation from arable land to water area was the major land use transformation type improving the eco-environmental quality.
