固原上黄试区土地利用动态监测与分析评价

Trends Monitor and Analytical Evaluation of Land Utilization in Shanghuang Experimental Area of Guyuan

本文在分析了上黄试区土地类型的基础上，利用遥感制图方法，对近１３年土地利用进行了动态监测。结果表明，１９９５年林地和基本农田，分别比１９８２年增长１４．４倍和２．１倍，人均林地０．２９ｈｍ２，人工草地０．０８ｈｍ２，基本农田０．３ｈｍ２，农业生态环境和基础条件得到根本改善，土地生产力成倍提高，从而为发展高效农业创造了良好的生态环境。

In the paper, on the basis of analysing land type of Shanghuang experimental area, using the method of remote sensing map-making, we have been to trend monitor in progress to land utilization for recent 13 years. the results showed, the area of forest land and basic farmland in 1995 increased partly 14. 4 and 2. 1 times than that in 1982, personal forest land was 0. 29hm2, artificial grassland was 0. 08hm2, basic farmland was 0. 3hm2, environment and basic condition of agriculture and ecology got fundamental improvements, land productive forces had doubled and doubled, and thus had good environment condition for developing high effect agriculture.
