近20年和林格尔县植被覆盖变化研究

Study on the Change of Vegetation Coverage in Recent 20 Years in Helinger County

以和林格尔县遥感影像数据为基础,对植被覆盖展开相关研究分析,获取如下结论:①研究区以低覆盖度植被占主导地位,整体上植被生态系统较脆弱;②各景观类型差异性较小,但各类型间存在微弱增大的现象;中覆盖度植被破碎化程度最高,整体上各覆盖类型由破碎化、零散化趋于规则化、整体化。

Based on the RS image data of Helinger, vegetation coverage of the local area was studied, and the following conclusions were got ： （a） low-coverage vegetation dominates the study area, the overall vegetation ecosystem＇is fragile; （b） different landscape types show less differences, but the differences are increasing slightly; medium-coverage vegetation shows the highest fragmentation degree, as a whole, all coverage types turn from fragmented.and scattered to regular and integrated.
