辽东山区是辽宁省重要的水源涵养基地和中部城市群的天然绿色屏障,在退耕还林过程中选择不同的植被恢复模式对退耕地植被群落的发育演替、生态功能的发挥具有不同的作用。文章通过对草河口退耕还林监测场植被恢复不同模式连续3年的调查研究认为,辽东山区在坡耕地退耕之初的几年内,植被自然恢复比较快,生态功能也比较强,但人工辅助措施能加快植被恢复进程,尤其是乔灌模式植被群落发育最好,为生态功能的发挥提供了必要的物质基础。
The Liaodong mountainous area is a natural green barrier of important water conservation base and central urban agglomeration in Liaoning Province. Different vegetation restoration modes during the process of returning farmland to forest have different effects on the development succession and ecological function of vegetation communities. Through the investigation of different patterns of vegetation restoration in the Grassland on the returning farmland to forest project for three years in a row, the author believes that within a few years of returning farmland to slope farmland in Liaodong Mountainous Area, the natural recovery of vegetation is faster and the ecological function is stronger. However, It can speed up the process of vegetation restoration, especially the best vegetation in the arbor-shrub irrigation model, which provides the necessary material foundation for the ecological function.
