摘要

[目的] 探究塔里木河中游荒漠绿洲过渡带——肖塘地区的土地利用动态变化特征及其对荒漠林地动态格局的影响

为该区域土地资源合理利用以及荒漠林资源保护提供理论依据。[方法] 根据肖塘地区1973-2010年4期遥感影像解译数据进行荒漠林地动态变化分析。[结果] 荒漠林地从1973年占整个研究区面积的21.9%到2010年的16.9%

成为研究区变幅最大的土地利用类型。1973-2010年荒漠林地面积减少了13.19%

主要转变为农田

而且其年变化速率不断增大。[结论] 近40 a来

随着人类对肖塘地区持续的水土开发

研究区内荒漠林地处于持续退化的状态。天然植被的退化会进一步对该区域的生态安全构成威胁。

Abstract

[Objective] The characteristics of land use change and its influence on desert woodland dynamic pattern of desert oasis ecotone in the middle reaches of the Tarim River Xiaotang area were analyzed in order to provide theoretical foundation for rational utilization of land resources and protection of desert woodland resources. [Methods] Based on the data interpreted from 4 remote sensing images in different periods from 1973 to 2010

the dynamics of desert woodland was analyzed. [Results] The coverage of desert woodland decreased from 21.9% in 1973 to 16.9% in year 2010

and was the most varied land use pattern. From 1973 to 2010

desert woodland decreased by 13.19%

mainly transformed into farmland

and the annual change rate had increasing trend. [Conclusion] In recent 40 years

resulted from the continuous soil development by human

the desert woodland in the research area was in a constant state of degradation

and it might further pose some threats to the region's ecological security.
