【摘要】：依據(jù)文獻和實地調(diào)研,借助于專業(yè)版的谷歌地球和太樂地圖,人機交互勾繪獲得6個世園公園(昆明、沈陽、臺北、西安、青島和唐山)的邊界數(shù)據(jù)和鳥瞰圖。以2015年或2016年夏季過境的Landsat衛(wèi)星影像為數(shù)據(jù)源,運用ENVI軟件計算出6個世園公園的NDVI、MNDWI、IBI和LST,以降溫距離和冷島強度衡量世園公園夏季降溫效果,通過外部緩沖區(qū)距離梯度分析,初步確定了6個世園公園冷島效應的有效距離。剖面分析與主成分分析表明6個世園公園均表現(xiàn)為LST與NDVI、MNDWI呈負相關,與IBI正相關;NDVI與IBI、MNDWI呈負相關,除西安、臺北世園公園外,IBI與MNDWI之間為正相關。相關性分析表明,6個世園公園的降溫距離、冷島強度與其總面積、水體面積、綠地面積、邊界長度和LSI呈正相關,與不透水面面積、SHEI呈負相關,該結果對熱島緩解型公共綠地的規(guī)劃與建設,有一定的理論和實踐啟示。
[Abstract]:According to the literature and field research, with the help of the professional Google Earth and Tai Le maps, six parks of Shiyuan (Kunming, Shenyang, Taipei, Xi'an, Kunming, Shenyang, Taipei, Xi'an) were drawn by human-computer interaction. The boundary data and aerial view of Qingdao and Tangshan. The data source is Landsat satellite images that transit in the summer of 2015 or 2016. The ENVI software was used to calculate the NDVI MNDWIIIBI and LST of the six parks. The cooling effect of the park in summer was evaluated by the cooling distance and the intensity of the cold island. The distance gradient analysis of the outer buffer zone was carried out. The effective distance of cold island effect in 6 parks was preliminarily determined. The results of profile analysis and principal component analysis showed that LST was negatively correlated with NDVI MNDWI, and positively correlated with IBI with IBI MNDWI, with the exception of Xi'an. The correlation analysis showed that the cooling distance, cold island intensity and total area, water body area, green space area, boundary length and LSI were positively correlated with the temperature drop distance and the intensity of cold island in the six parks. There is a negative correlation between SHEI and the area of impermeable surface area. This result has some theoretical and practical implications for the planning and construction of public green land of heat island relief type.
