移民安置综合开发区土地利用变化及驱动力分析——以疏勒河中游干流区为例

Analysis on land use variation and its driving force of comprehensive development region for immigrant settlement——a case of main stream region of Mid-Shulehe River

分析移民安置综合开发区土地利用变化与驱动力对于揭示人类活动与气候变化对土地利用影响具有重要科学意义。为此,以疏勒河中游干流移民安置区为例,利用GIS和RS技术分析区域内从1970—2013年土地利用变化特征,基于景观指数分析了不同年代土地利用类型的变化特点。基于移民城乡建设、农业耕地开发、农田水利建设、生态治理和气候变化等五个方面分析了对区域土地利用的影响,并结合不同土地利用相互转化关系定量分析了五个驱动力的贡献程度,从而系统全面地揭示了移民安置区土地利用变化与驱动力的相互关系,为构建区域生态屏障保护技术提供基础支撑。

The analysis of the land use variation and its driving force of comprehensive development region for immigrant settlement have important scientific significances for revealing the impacts from human activities and climate change on land use.Therefore,the main stream region of the Mid-Shulehe River for immigrant settlement is taken as the study case for analyzing the variation characteristics of the land use within the region from 1970 to 2013 through the techniques of GIS and RS,and then the variation characteristics of the land uses in different years are analyzed in accordance with the relevant landscape indexes.Based on the five aspects of urban-rural construction,agricultural land development,construction of farmland irrigation and water conservancy,ecological improvement and climate change,the impacts on the regional land use are analyzed,while the contribution degrees from the five driving forces mentioned above are quantitatively analyzed in combination with the mutual transformation relationships among all the different land uses,thus the relationship between the variation and its driving force of the land use of the immigrant settlement region is systematically and fully revealed,which provides a basic support for the protection technology of building up the regional ecological barrier.
