新疆北疆地区景观生态类型分类初探：以新疆沙湾县为例

1　前　　言新疆生态环境的现状喜忧参半,绿洲内部生态环境得到改善,但沙漠化过程不断加剧,成为新疆生态环境良性循环的极大隐患。景观生态学以综合整体的思想审视生态环境的现状和变化,为我们更成功地解决所面临的生态问题提供了新的理论和方法。本文试图在新疆沙湾县生态环境监测工作的基础上,提出适宜于新疆北疆地区的景观生态类型分类系统,以便更好地认识、利用和管理各类景观,达到人地共生和持续发展的目的。2　沙湾县环境概况沙湾县地处北疆天山中部的依连哈比尔尕山北麓与准噶尔盆地南缘之间,界于Ｅ84°57′～86°09′和Ｎ43°20′～…

A Preliminary Study on Landscape Classification of the Northern Xinjiang RegionA Case Study of Shawan County.

Shawan county is located in the northern slope of Tianshan Mountains and the south fringe of Junggur Basin. The county's economy gives first place to agriculture combining with animal husbandry. The landscape features is of representative in Northern Xinjiang. On the basis of heterogeneity and hierarchy of landscape ecological system,the landscape classification system of the Northern Xinjiang was presented. In our plan,law of regional disparities,man-made disturbance and landscape ecological differentiation were considered as classification principle. Landscape units at different level were adopted. 2 landscape types,7 subtypes,14 classes,28 groups and 75landscape units were divided.
