新疆和田河流域1990—2015年景观动态变化研究

Research on dynamic changes of landscape in Xinjiang Hotan River Basin from 1990 to 2015

本文利用RS和GIS技术,探讨了和田河流域1990—2015年土地利用变化过程与景观格局的关系。结果表明:近25年来,研究区耕地景观优势度下降,景观形状趋于规则;林地景观优势度增强,斑块分布趋于集中;草地景观优势度下降,斑块趋于破碎化;水域斑块分布趋于分散。研究区整体景观呈现破碎化,受人类活动干扰较强。

RS and GIS technologies are utilized in the paper for discussing the relationship of land use change process and landscape pattern in Hoton River Basin from 1990 to 2015. The results show that the superiority- of cultivated land landscape in the study area has decreased in the past 25 years, and the landscape shape tends to be regular. The forest landscape superiority- is enhanced, the patch distribution tends to be concentrated, the superiority- of grassland landscape is decreased, and the patches tend to break up, the distribution of water patches tends to disperse. The whole landscape of the study area is fragmented and highly disturbed by human activities
