The sustainable development of land resources is important integrant of strategic objective of in China. Along with fast raise of population and development of economy and society, a shortage of land resources due to multi- factor has lead to worry on land ecological safe, therefore sustainable development and exploitation potentialities of land resources is certain to carry weight.

土地的可持续利用是实现我国可持续发展战略目标的重要组成部分，随着人口的急剧增加和经济社会的快速发展，由各种因子导致的土地资源供给的短缺已引起人们对土地资源生态安全的担忧，因此也更为重视土地的深度挖潜和持续利用。

The result shows that desertification is serious in the study area. Various types of desertification land add up to 370000hm~2, accounting for 39% of the total land. From l995 to 2000,the serious desertification land, where vegetation cover is below 30%, extends with the speed of 61hm~2 per year. The increasing landscape fragment reflects the intense intervene that human activities act on landscape. Shape index changes indicate the growing ratio of interior -edge, which is disadvantageous to natural recover of land.

结果表明，研究地区沙漠化现象严重，各种类型沙漠化土地总面积37万hm~2占总土地面积的39％；植被盖度小于 30％的较严重的沙漠化土地从1995年到2000年的五年间以61hm~2／年的速度扩展；景观破碎度变大，反映出人类活动对景观的干预作用不断增强；沙漠化景观要素的形状指数变化表现出内、缘比变大，不利于沙漠化土地的自然恢复。

The results showed that there were significant differences among parameters of texture feature of the different land utilization. In the desertification, the mean and variance were comparatively high. The gray level was asymmetry, the contrasts between neighboring pixels were significant; while in water and irrigable land, the mean, variance was a little bit low, the grey level was symmetry; the mean, variance and gray level in the forest and dry land was between the above (desertification and water and irrigable land).

不同土地利用类型之间纹理特征参数差异明显，荒漠化土地的均值、方差值较高，灰度分布不均匀，相邻像元反差明显，内部变化剧烈；水体和灌溉耕地的均值、方差值很低，灰度值均匀，内部变化小；林地和旱耕地信息介于上述两类土地之间。

In order to carry out praedial master plan efficiently, it's necessary to analyse and control existing land utilization. Our first task is to take advantage of arable land. Along with expanding economy, the increasing of population, the faster infrastructure construction and unceasing development of countryside, the demand of land is higher and higher. It made a big stress for the limited land resource.
