中文摘要:
      随着城市化进程的不断加快,建设用地扩张迅速,不合理的城市扩展模式会干扰区域经济与生态之间的协调发展,引发资源利用不合理、生态环境恶化等负面效应。利用移动窗口法、MCR模型、Hydrology扩展模块相结合,得到武汉市适宜扩张路径、生态安全路径,为未来城市规划提供了借鉴。结果表明:(1)适宜建设区(适宜扩张区、优化建设区)所占比例达6059%,说明目前城市发展格局较为合理;(2)不同的适宜性分区对于建设活动的要求不同,适宜建设区域可引导进行建设开发活动,禁止建设区、生态恢复区应设立相关政策,严禁开发;(3)“山谷线”作为建设用地的适宜扩展路径,“山脊线”作为生态安全路径,可避免建设用地盲目扩张,为城市建设指明了方向;(4)生态关键点对于维护城市的生态安全至关重要,应制定相关措施,进行有效管理。
英文摘要:
      With the rapid development of urbanization and the rapid expansion of construction land,unreasonable urban expansion mode will interfere with the coordinated development between regional economy and ecology,and lead to unreasonable resource utilization and ecological environment deterioration.This paper uses the moving split window method,MCR model and hydrologic expansion module to get the appropriate expansion path and ecological security path of Wuhan,which provides a reference for future urban planning.The results show that:(1) the proportion of suitable construction area (suitable area for expansion and optimized building area) reaches 60.59%,which indicates that the current urban development pattern is relatively reasonable.(2)Different suitability areas have different requirements for construction activities.The suitable construction area can be guided to carry out construction and development activities and relevant policies should be set up for construction areas and ecological restoration areas to make sure development is strictly prohibited in these areas.(3)Making the “Valley line” a suitable route for construction land expansion and the “ridge line” an ecological safety path can avoid blind expansion of construction land and point out the direction for urban construction.(4) Ecological key points are of great importance for maintaining urban ecological security,so relevant measures should be formulated for effective management.
