| 摘 要： | 根据中国北方地区人类活动对地表组成物质的扰动特征,将中国北方沙质荒漠化土地治理区划分为绿洲周缘农业型沙质荒漠化、农牧交错带农牧型沙质荒漠化、草原牧业型沙质荒漠化三种类型;利用1975年M SS卫星图像数据和2000年ETM卫星图像数据为信息源,在M APG IS软件支持下,采用人机交互方法对沙质荒漠化土地类型进行信息提取,编制研究区1975年和2000年沙质荒漠化土地类型分布图,在根据沙质荒漠化土地类型的变化幅度确定沙质荒漠化土地变化类型的基础上,通过1975年和2000年沙质荒漠化土地类型分布图的叠加分析,查明了中国北方近25年来沙质荒漠化土地的时空演化规律,结合中国北方不同沙质荒漠化土地治理区的自然条件和人类活动特征,提出了中国北方沙质荒漠化土地治理建议。

| Abstract: | According as the rule of human activity influence on surface components of crust,we partition the sandy desertification land management area in North China into agriculture surrounding sandy desertification,stockbreeding and agriculture interleaved sandy desertification and grassland stockbreeding sandy desertification.Using MSS satellite image data in 1975 and ETM image data in 2000 as remote sensing information source,under the support of MAPGIS system,assisted by human operation we did the classification of change type of sandy desertification,and developed the change type of sandy desertification distribution map in 1975 and 2000 of the workaround.Based on the change range of sandy desertification land we plot out the type change of sandy desertification land. Through the overlapping analysis of type change of sandy desertification land in 1975 and 2000,we studied the dynamic change of sandy desertification in North China in the last 25 years,combined with the feature of nature condition and human activity of different area of sandy desertification land,we tabled a proposal of sandy desertification land management and control. |
