摘要
为评价我国西南山区景观稳定状况,基于2000年和2015年Landsat遥感影像,以乌江中上游为例,从基质稳定性、斑块特征稳定性和斑块密度稳定性3个方面对流域景观稳定性进行分析。结果表明:2000—2015年,景观基质稳定性呈下降趋势。景观斑块特征稳定性呈裸地>灌木林>草地>水域>森林>耕地>建设用地。景观斑块密度稳定性呈裸地>灌木林>草地>森林>水域>建设用地>耕地。流域景观基质稳定性、斑块特征稳定性和斑块密度稳定性指数空间异质性突出。生态治理工程及快速经济发展是影响乌江中上游景观稳定性的主要因素。
In order to evaluate the landscape stability in mountainous area of southwest China,this paper analyzed the landscape stability in middle and upper reaches of the Wujiang River from three aspects of landscape matrix stability,landscape patch stability and landscape density stability based on the Landsat remote-sensing images in2000and2015.The results showed that the landscape stability decreased during the period from2000to2015.Landscape patch stability showed the characteristics of bare land>shrubbery>grass>water>forest>plantation>built-up land.Landscape density stability showed the characteristics of bare land>shrubbery>grass>forest>water>built-up land>plantation.There were significant spatial heterogeneities for landscape matrix stability,landscape patch stability and landscape density stability in each watershed.Ecological projects and rapid economic development are dominant factors affecting landscape stability in middle and upper reaches of the Wujiang River.
