摘　　要：研究目的:应用碳氧平衡法探讨区域生态用地需求量的测算方法,为编制土地利用总体规划提供科学依据。研究方法:碳氧平衡法,生态服务功能法。研究结果:空气中的碳氧平衡是在不断调整绿色植物和多种释碳耗氧关系基础上实现的。研究二氧化碳和氧气的消耗与供应关系及其分配特征,有助于测算生态用地需求量。应用上述方法开展了测算郑州市2010年生态用地需求量实证研究。研究结论:解决生态用地需求量预测必须界定"生态用地"的概念和区分土地生态功能多元性。研究表明基于碳氧平衡法测算区域生态用地需求量的方法是可行的,具有可操作性。应当从生态用地角度重新审视土地利用现状分类体系,使其完善。The aim of this paper is to provide scientific foundation for comprehensive land use planning by probing into the method of carbon-oxygen balance in estimation of ecological land demand in order to achieve environmental goals of the planning. Methods of Carbon - Oxygen balance and ecological service value were employed. Result show that the Carbon -Oxygen balance is achieved by continually adjusting green plant and multi-connection of releasing Carbon-Oxygen consumption. The study on consume-purvey connection and distributive character is conducive to the estimation of ecological land demand. The ecological land demand of Zhengzhou in 2010 was estimated with the above methods. The conclusions include that the concept of ecological land and multi-ecological functions of land should be clearly defined before the estimation of ecological land demand. The method of carbon-oxygen balance is feasible and operable. The current land classification system shall re-defined from the viewpoint of ecological land demand in order to make it mature
