- 摘要:
- 为防止土地资源的不合理利用引起湖泊生态系统失衡特别是水环境恶化等问题，采用地域分异规律，运用规划的理论和方法，构建了梁子湖生态屏障区四种土地利用模式，并对其土地利用布局调整进行了模拟分析。结果表明：调整后屏障区的土地利用斑块数减少了67.3%，土地利用破碎度显著降低，具有重要生态功能的耕地、林地、坑塘水面等用地类型的布局更趋合理；经过土地利用布局调整后的屏障区形成梁子湖外围封闭的环状缓冲带，可以更好地发挥其生态系统服务功能，有效阻隔外部因素对梁子湖产生的不利影响。
- Abstract:
- In order to prevent unreasonable use of land resources causing lake ecosystem imbalances in particular the deterioration of water environment, presents geographical differentiation regulation and utilizes planning theories and methods was presented, four kinds of land use patterns in ecological shelter zone was constructed of Liangzi Lake, and some simulation analysis on the adjustment of the land use layout was made. The result shows that the number of land use blocks of adjusted shelter zone has been reduced by 67.3%; the fragmentation of land use has been significantly reduced; the layout of farmland, woodland and pond water, with important ecological functions, is becoming more and more reasonable. The closed ring shelter zone around Liangzi Lake formed by shelter zone after land use layout adjustment would play a better role of the ecological shelter zone in Liangzi Lake ecosystem services and prevent the adverse impacts caused by external factors.
