摘要
文章利用GIS、景观生态原理和景观格局指数对合肥市各区绿地景观的空间结构、功能及异质性进行了研究和分析。结果表明,单位附属绿地的景观多样性指数最高,蜀山区达到了4.871;公园或游园的景观多样性指数最低,瑶海区0.547为最小;合肥市各区景观优势度指数均以单位附属绿地最高,蜀山区3.654为最高。分析表明合肥市绿地系统总体结构合理,蜀山区景观结构最合理,庐阳区和包河区次之;另外,对不同类型景观的小气候效应进行了分析;白天各景观类型的最高温度的排列次序是:林地>草地>裸地;在各时段,林地的相对湿度均高于裸地,最大幅度为20%,最小幅度为12%;研究结果为合肥城市绿地结构的合理布局和城市建设提供依据。
Employing GIS, principles of landscape ecology and indices of landscape patterns, spatial structure, function and the heterogeneity of urban landscape of Hefei are studied and analyzed. The results show that diversity index of accessory greenbelt was highest, 4. 871 for Shushan district ; the diversity index of.park or garden was lowest, 0. 547 for Yaohai district respectively. Comparing to other types of landscape, the dominance of accessory greenbelt in four districts of Hefei were highest. Shushan district tops all the rest, which was 3. 654 particularly. In general, the structure of green space of Hefei was reasonable. In addition, the microclimate effects of different types of landscape are analyzed. At daytime, the maximum temperature of woodland was higher than that of lawn, and in turn, the maximum temperature of lawn was higher than that of barren land. The relative humidity of the woodland was higher than the barren land, the maximum extent was 20%, the minimum extent was 12%. The results of this research provide references in the rational distribution and construction of urban green space of Hefei.
