中文摘要	利用遥感技术对喀什河流域景观进行分析,综合景观密度、景观比例和优势度值三个指数构造了景观类型结构特征因子反映景观稳定性,应用生物生产力因子来反映生态稳定性,应用土地利用因子来反映人为活动影响水平,利用这三个因子借助综合指数法进行喀什河流域景观生态综合评价研究。结果表明: 1)喀什河流域是以自然生态系统为主,伴有较轻人为干扰痕迹,生态系统的生物生产力和稳定性较好; 2)流域景观生态质量为5级以上的占主体(82. 08%),其中6级所占总面积的56. 63%,说明景观生态较好。
英文摘要	By using remote sensing images,the landscape type and landscape structure of Kashi River basin were analyzed. Net primary productivityNPP)and biomass were calculated. Land use factor,ecological stability factor and landscape structure factor which are composed of landscape density,landscape ratio and dominance, were used to evaluate the basin ecological environment. And also the inundating effect of three reservoirs on landscape ecology was studied. The results show that :1)Integrated dominance of mountain landscape is 82. 42%,oasis is 17. 58%,and the artificial landscape dominance is 17. 5% which is significantly lower than the natural landscape. Net primary productivity of the Kashi river basin is between 410 to 497 /(m~2·a)which belongs to temperate grassland ecosystem. The basin is in a higher biomass level with good ecological stability.2)Integrated landscape indices above fifth grade occupy 82. 08%,in which sixth grade is about 56. 63% of total area. That means ecological landscape of Kashi river basin is better.
