矿区废弃地复垦的景观生态规划与设计

THE LANDSCAPE ECOLOGICAL PLANNING AND DESIGN OF DEPLETED MINED LAND

景观生态学属于宏观尺度生态空间研究范畴，理论核心集中表现为空间异质性和生态整体性两方面。基于景观生态规划与设计的生态重建就是使采矿废弃地具有具体利用方式和一定水平的生产力，维持相对稳定的生态平衡，与周围景观特征相协调，最终达到生态整体性目标。矿区废弃地有多种类型，不同类型具有不同的生态重建途径。矿区废弃地隶属各种尺度的景观类型，只有按照景观生态学原理，在宏观上设计出合理的景观格局，在微观上创造出适合的生态条件，即依靠景观生态规划与设计，才能实现生态重建目标。

Landscpae ecology belongs to the macro ecological spatial studies and its theoretical focuses are spatial heterogeneity and ecological holism.The rehabilitation based on landscape ecological planning and design is to reasonably use depleted mined land and make it properly productive,to keep its relatively stable ecological equlibrium and coordinate it with its surroundings,in order to attain the goal of ecological holism.Depleted mined land can be classified as diverse types,and there are different ways of rehabilitation for different land types.Meanwhile depleted mined land is also concerned with different landscape scale.Therefore,only by working out reasonable macro landscape patterns and set up suitable micro ecological conditions based on landscape ecology,can the goal of rehabilitation be realized.
