| 摘 要： | 利用Quickbird和ETM影像对浙江省绍兴县北部平原220 km2区域内50个村庄景观格局热效应进行研究.通过5种地类斑块共45个景观指数之间、景观指数与环境亮温之间的数量关系分析表明:在核心区,各景观指数与环境亮温间具有良好的线性关系,相关性大小受地类斑块相对面积的影响明显;众多景观指数可分为破碎度类指数、覆盖率类指数、形状指数、核心区规模指数、100m缓冲区相关指数等几类,其中优势斑块和景观总体的破碎度类指数、覆盖率类指数是环境亮温的主要作用因子;该区景观复杂,景观结构指数对亮温的贡献约占总量的25%,数量结构指数对亮温的贡献约占75%.建立2个亮温多元线性模型,筛选出相应的亮温预测及调控因子组,结果显示在景观斑块数量结构一定的情况下,地类斑块边界稠密、众多小斑块均匀分布、增温斑块形状狭长、降温斑块形状圆满的村庄更有助于环境降温.在核心区+100,+200,+300m缓冲区,环境亮温的主导因子变为绿地水体覆盖率,村庄景观格局热效应问题的研究尺度以核心区+100m缓冲区范围为佳. |

| Abstract: | A thermal effect of landscape patterns from 50 villages within a 220 km2 plain region in northern Shaoxing,Zhejiang Province was studied based on Quickbird and ETM images data.A total 45 landscape pattern indices(LPI) from 5 land-use types of patches were calculated,and the quantity relationship among LPI and between LPI and environment brightness temperature(EBT) were analyzed.The result showed that in the core area(built-up area) of villages,there was a close linear relationship between LPI and BET;and th... |
