伊犁喀什河流域生态景观格局分析

Analysis of Ecological Landscape Pattern in Kashi River Basin of Yili

通过景观生态学的分类方法,结合遥感,对喀什河上的景观进行分类分析,结果表明,喀什河全流域山地景观的优势度显著大于绿洲景观的优势度。山地草原草甸景观具有最大的景观优势度,其次就是山地林地景观。对于绿洲景观,农田和水域景观是优势度最高的,其次就是河谷草地与河谷林地景观。在整个喀什河流域中,山地草原草甸景观是优势景观。对喀什河流域上游区域来说,山地景观依然是优势景观,山地草原草甸景观具有最大的景观优势度,其次就是山地林地景观与山地裸岩景观。总的来说,喀什河流域中有植被覆盖的景观类占绝对优势,这反映了区域整体生态环境状况较好。

This study was analyzed landscape classification in Kashi River by the classification method of landscape ecology and remote sensing. The results showed that the landscape dominance of mountainous region is larger than that of oasis landscape in the Kashi River basin; in which. landscape dominance of mountain meadow is first, and mountain woodland landscape second. For oasis landscape, landscape of famland and water area is of the highest dominance, with river valley meadow and woodland landscape follows. Mountain prairie and mountain meadow landscape are dominant landscape in whole Kashi river basin. Mountain landscape is also dominant landscape in upper reaches of Kashi River, landscape domi nance of mountain meadow is also most apparently, the second is mountain woodland and mountain bare rocks landscape. In a word. this kind of landscape covered by vegetation takes absolute dominant landscape in the whole basin of Kashi River, reflecting ecological environment is bette ring in the region.
