From the perspective of climatic and geographical features, this study analyzed spatial layouts, outer appearance, courtyard layout and material structure of vernacular dwellings in Guanzhong-Tianshui area, and refined the ecological concepts and technologies adaptive to local environment. Vernacular dwellings are expected to develop sustainably in the evolution of natural environment, and adapt to the development needs of local human settlements.展开更多
净第一性生产力是表现陆地生态过程的关键参数,土地利用变化深刻影响区域的净第一性生产力。选取关中-天水经济区为研究区域,尝试对30 m精度的1980-2011年4期9月份左右Landsat 7的遥感影像以及CASA模型来估算关中-天水经济区的净第一性...净第一性生产力是表现陆地生态过程的关键参数,土地利用变化深刻影响区域的净第一性生产力。选取关中-天水经济区为研究区域,尝试对30 m精度的1980-2011年4期9月份左右Landsat 7的遥感影像以及CASA模型来估算关中-天水经济区的净第一性生产力,并用2011年遥感图像解译获得该年的土地利用数据,以及土地利用变化情况。在此基础上分析土地利用变化对净第一性生产力的影响,并且对关天经济区各县市净初级生产力进行了对比和分析。结果表明:1980-2011年,关中-天水经济区土地利用耕地、林地、居民建筑用地变化明显,南部秦岭山区多为林地与草地,净第一性生产力高达625.37 g C·m-2·a-1,而关中平原与天水地区人口居住区与开垦区净第一性生产力明显下降,最低达47.78 g C·m-2·a-1,人为的开发与利用土地降低了区域的净第一性生产力。所以,要继续施行落实退耕还林政策,控制城镇用地较大速度的扩增,以保持好区域的生态服务功能。展开更多
