绿地格局与温度的关系──以太原市为例

Relationship Between Green Space Pattern and Temperature: A Case Study of Taiyuan

研究旨在按照既定的尺度研究绿地格局与温度之间的关系。绿地格局利用绿地格局指数来做表征,从斑块规模、边界特征、空间特征3方面来选取指数,温度利用遥感影像反演得到。结果表明:斑块数量超过400时,平均斑块面积和斑块面积的离散度在一定区域变化时,温度才会下降。平均斑块的边界复杂度保持在一定区域变化时,温度才会下降。空间位置的结果也表明当平均邻近指数和平均邻近距离保持在一定区域变化时,温度才会下降。研究结果对建设城市绿地有一定的实践指导意义。

The study aims to study the relationship between green space pattern and temperature according tothe established scale. The pattern of green space was calculated by green space pattern index, the index wasdetermined by patch size, boundary characteristics and spatial characteristics, and inversion temperature wasobtained by remote sensing images. The results showed that when the patch number was above 400 and thedispersion of average patch area and patch area changed within a certain range, the temperature could drop.When the average patch boundary complexity was kept within a certain range, the temperature could drop. Theresults of spatial location also showed that when the average index and the average distance changed within acertain range, the temperature could drop. The results have guiding significances for the construction of urbangreen space.
