摘要
本文选择大连市沙河口和西岗区为研究区,以Landsat ETM、SPOT等数据为基础,通过遥感解译和反演得到1999年和2013年研究区内绿地及地表温度空间分布及演变特征,结合温度-植被指数(TVX)空间分析法测度城区发展过程中绿色空间减退所引起的热环境效应,以提出更有针对性的城市气候变化适应性规划。研究结果表明:(1)1999-2013年,研究区绿地面积减少43.8%,绿地斑块增加42.9%,城市绿地呈现面积减少、空间分布碎化的演变特征。其中,森林绿地、公园绿地和街区绿地转化为建设用地的贡献率分别为43.8%、42.9%和13.3%,街区绿地因原始面积小且转化率高,被建设用地侵占最为严重。(2)1999-2013年,研究区地表温度最高值上升5.2 K,地表温差增加1.7 K,地温聚集区间由301.6~304.7 K上升至306.5~310.9 K,热环境效应加剧。(3)TVX模型追踪结果显示,快速城市化过程中研究区内城市绿地转化为建设用地引起植被覆盖度下降和地表温度上升,其中街区绿地被侵占造成的地表热环境效应大于公园绿地和森林绿地。
