应用3S技术与景观格局分析方法,研究了1977～2000年青海湖流域草地景观格局变化.结果表明:1977～2000年,青海湖流域草地景观格局变化呈现斑块数目减少,景观破碎度和分离度下降,平均斑块面积与分维数增加的趋势;从流域内县域景观变化分析,天峻、刚察、海晏县草地景观结构呈现出同样的变化趋势;但共和县1977～2000年草地斑块数目、景观破碎度与分离度增加,平均斑块面积减少,草地景观结构呈现出相反的变化趋势.

The changes of grassland landscape pattern in Qinghai Lake watershed form 1977 to 2000 were studied by the method of 3S and landscape pattern analysis. The results showed that patch numbers reduced, degree of landscape fragmentation and isolation decreased, average patch area and fractal dimension increased; Form analyzing the landscape change of county area in Qinghai Lake watershed, the landscape structure of Tianjun, Gangcha, Haiyan had same change; But Gonghe had the different change, such as average patch, landscape fragmentation and resolution increased, average patch area decreased.
