摘要
随着社会城镇化进程加快,人与生态平衡的矛盾日益凸显。如何在保障生态安全的背景下,寻求经济生态双赢的可持续发展模式便成为这个时代所面临的重要课题。木兰县是黑龙江省重要的林特产品和农粮产业基地,文中以木兰县为研究区域,利用RS和GIS手段,对木兰县生态格局时空变化进行定性和定量的分析研究。研究结果表明:2006—2017年生态系统图斑破碎,城镇和裸地生态系统的土地利用动态度较高,人为干预强度大;生态系统流动方向主要是城镇生态系统、农田生态系统和森林生态系统之间的转化,且城镇生态面积增加量最高。同时,结合当地情况,对当地生态格局变化产生的问题提出解决对策,为日后的生态安全体系的构建和布局优化以及生态可持续发展提供参考依据。
With societal process accelerating, the contradiction between people and ecological balance has to be increasingly stressed. At the background of protecting the ecological security, how to seek economy and ecology with both of winner sustainable development model has become an important issue facing this era. Mulan County is an important base that is forest products and agricultural products processing industry in Heilongjiang Province. In this paper, the temporal and spatial change of ecological pattern as the research area of Mulan County are qualitatively and quantitatively analyzed by using RS and GIS. The result shows that: in 2006-2017, the figure spots of ecosystem were broken, and the land use efficiency of urban and bare land's ecosystem were high. This was because the intensity of human intervention was strong. The direction of ecosystem's flow was mainly between urban ecosystem, farmland ecosystem and forest ecosystem, and the increment of urban ecological area was the highest. At the same time, according to the local situation, solutions of the local ecological pattern changes caused question is proposed,which can provide a reference comment of ecological security system established, layout optimized and ecological sustainable development is also provided for the future.
