| 摘 要： | 选择位于北京中关村生命科技园区的休闲广场为研究区来探讨小尺度城市边缘区景观格局与小气候环境因子相关性,基于SPOT卫星数据和实地小气候观测数据进行计算和分析,结果表明:各种绿地类型要比相同观测期内的非绿地覆盖的土地利用类型温度低,湿度大;景观多样性指数与各小气候因子相关系数R2基本接近于1,表明二者有极显著的相关性;而边界密度指数、斑块密度指数和形状指数与各小气候环境因子的相关程度的显著性差异比较大:14:00地温与形状指数相关系数R2大于0.8的占77.78%;气温与边界密度指数和斑块密度指数的相关系数R2大于0.8都占66.67%;相对湿度与形状指数的相关程度8:00要比14:00显著(8:00相关系数R2大于0.8的占55.56%),该研究结果证实了景观格局与环境因子确实存在着复杂的非线型关系。

| Abstract: | The article focused on the recreational square of Zhongguancun Life Science where different landscape types were classified by Arcview3.2 on SPOT image data,and microclimate environmental factors were observed.Then landscape pattern indexes were calculated by Fragstas3.1,and relativity between environmental factors and landscape pattern indexes were analyzed by SPSS.The results indicated that different types of green land have the characteristics of lower temperature and higher humidity,compared with other ... |
