松嫩平原土地利用变化的聚类分析

Cluster Analysis on Land Use Change in the Songnen Plain

在松嫩平原1989年和2004年土地利用TM卫星影像遥感解译的基础上,对该区土地利用变化进行数量变化和转移矩阵分析,揭示松嫩平原土地利用变化的主要特点。应用数据统计软件SPSS,对全区21市县土地利用变化进行聚类分析,将全区分为8个分区:综合治理区、草原保护区、沙碱并治区、退耕还草区、湿地保护区、水田发展区、环境待改善区和环境较好区。根据8个分区的特点,因地制宜,提出合理的对策和建议,供相关部门参考。

Based on the RS-interpreted images of land use in the Songnen Plain in 1989 and 2004, in this paper the areas and the transfer matrix of land use change in the plain are analyzed, and the main characteristics of land use change in plain are revealed. A cluster analysis of land use change in 21 cities and counties is carried out by applying SPSS statistical software. The study area is divided into 8 kinds, i.e. the comprehensive management are- as, grassland reserves, desertification and salinization controlling-improving areas, areas of returning land for farming to grassplots, wetland reserves, paddy field development areas, entironment improving areas and areas with fine entironment. Some rational strategies and suggestions are put forward for the relevant departments based on the actuality of land use change and the local conditions of the 8 kinds of areas, they are to enhance the water resources management and afforestation for water and soil conservation, improve the desertified and salinized lands, regenerate the natural vegetation, return land for farming to afforestation and grassplots, enhance the construetion of irriga- tion works, ete.
