摘　　要：指出了退耕还林工程是西部乃至中国生态建设的重要策略之一。重建与恢复植被不仅可以改变景观的类型组成,也影响着景观的空间格局。在景观生态学理论基础上,对各个地区景观变化研究资料进行了整理分析,结果表明:大部分地区在退耕还林建设的影响下,景观格局发生演变,耕地、林地景观格局得以优化调整,斑块复杂性和景观异质性程度降低,景观要素的空间联结加强,生态环境改善,但也存在着一些问题。针对这些问题给出了一些建议。Returning farmland to forest project is an important project in relation to the West and Chinese ecological restoration.Reconstruction and restoration of vegetation can not only change the landscape types,but also affects the spatial pattern of landscape.Combined with the theory of landscape ecology,this paper analyzes the previous research data on landscape change in various regions.The results show that under the influence of the construction of returning farmland to forests,the landscape pattern changes and the landscape pattern of cultivated land and forest land is optimized.The complexity and heterogeneity of landscape patch decreased;spatial relationship between landscape elements can be strengthened;the ecological environment is improved,but there are also some shortcomings.

关 键 词：退耕还林 景观格局 近自然林改造
