Abstract:

The landscape spatial feature, greenbelt landscape spatial feature and the grades and distribution of the patches in Shugang-Slender West Lake Scenic Spot were investigated by using geographic information system (GIS) with Quick bird image data. The results indicated: 1) The proportion of the horniness landscape area was large, and the usage of the land should be adjusted. 2) There were 2 979 patches of green-land in the research area. The area of these patches took up 6 528 227.0 m² and accounted for 53.36% of the total in the research area. The small patches (<500 m² in area) were more than the medium-large size patches and large size patches (>3 000 m² in area) while the latter ones had larger total area. 3) The green-land landscape diversity index was 0.559 5, evenness was 0.424 9, dominance was 0.394 8, contagion was 0.523 1, fragmentation was 0.456 0, green corridor density was 0.825 0 and fractal dimension was 1.148 1. 4) The distribution of the landscape was uneven, and diversity was not rich.
