摘要
黄土丘陵区生态环境极其脆弱,侵蚀严重,在分析该区小气候、土地利用方式、土壤特性和侵蚀特征的坡向差异及其成因的基础上,指出坡向差异在该区域耕作业、林业、牧业和水土保持措施方面的指导意义,并提出了一些合理利用这种差异及土地资源的建议,以其能为区域生态环境建设提供参考。
The eco-environment is extremely fragile in loess hilly area, and soil erosion is also serious. The differences of farming, forestry, grazing, soil characteristics and soil erosion in sunny slope and shady slope and its cause were analyzed, and the significance of these differences in local eco-environment construction was pointed out, also some suggestions on using these differences and soil resource were put forward, so that it can provide some references for the improvement of the eco-environment in this area.
