植被稀少的水土流失地区,大部分是处于半湿润、半干旱或干旱地区。起伏的地形和植被的稀少及降水较集中是造成水土流失的前提,加之土地利用不合理,形成了一系列侵蚀地貌,导致土壤肥力衰退、地下水位降低、耕地面积大幅度减少,并引起河流、水库水文状况的恶化,这种地区多是生态失调的。我省的朝阳地区、阜新大部分、铁岭、康平、昌图、法库局部,都是干旱或半干旱地区。尤其是西部山区,森林和植被已遭严重破坏,干旱灾害频繁,水土流失严重,致 Most of the soil erosion areas with poor vegetation are in semi-humid, semi-arid or arid areas. Rough terrain and vegetation are rare and precipitation is more concentrated is the prerequisite for soil erosion, combined with irrational use of land, forming a series of erosion landforms, leading to decline in soil fertility, groundwater levels decreased, arable land decreased significantly, and caused rivers, Hydrological conditions in the reservoir have deteriorated, and most of these areas are ecologically imbalanced. Most of the Fuxin, Tieling, Kangping, Changtu and Faku areas in our province’s Chaoyang area are mostly arid or semi-arid areas. In particular, in the western mountainous regions, forests and vegetation have been severely damaged. Droughts have been frequent and soil erosion has been so severe that they have caused
