小城镇园林绿化总量控制研究

运用系统论和生态要素阈值法,从小城镇人口承载力、碳氧平衡和水资源供应等生态要素方面,根据能量守恒与物质循环的原理,分析各个生态要素在系统平衡状态时的阈值,剖析小城镇生态平衡制约因素;同时,利用园林规划理论与生态学理论,对小城镇园林绿化总量进行了分析与论证,将生态要素阈值作为园林绿地规划指标的约束条件,基于小城镇生态系统可持续发展的目标,构建小城镇园林绿化总量控制模型,寻求小城镇适宜的园林绿化总量.

Study on Garden and Open Space Whole Scale Controlling of Small Towns

From the aspects of population carrying capacity, balance of carbon and oxygen and water resource provision at small town, this paper adopts system theory and ecological element threshold method, and analyzes the threshold of every ecological element in the balance of ecosystem on the basis of the principia of conversation of energy and circle of matter, it also anatomizes the sticking point of the ecosystem balance at small town. In order to find out the right scale of garden and open space at small town, it analyzes and demonstrates the right total scale of garden and open space by theories of garden planning and ecology, regards the threshold of ecological elements as restricting conditions of planning indexes of garden and open space, and builds a model of garden and open space whole scale controlling of Small town basing on the sustainable development of the ecosystem at small town.
