摘要
制定土地资源可持续性指标体系是“2 1世纪议程”中对各国提出的科学技术优先研究领域 ,为此国土资源部启动了中国土地资源可持续利用指标体系和评价方法研究。本文主要探讨制定区域性土地可持续利用指标体系的土地利用分区问题 ,服务于建立区域性指标体系 ,反映出不同区域土地可持续利用程度的不同评价标准和指标体系中指标类别的差异。根据分区基本依据 ,包括以自然特征和利用状况的相对一致性 ,注重使所划分的区域之间在重要指标或相同指标的阈值方面具有显著差异性 ,并兼顾行政区域的完整性 ,在全面分析不同区域的土地利用特性、生态环境条件、经济社会状况以及利用管理措施等基础上 ,进行全国土地利用分区。最终全国共划分出 1 0个土地利用区域 。
Developing indicator system of sustainability for land resources is one of the preferential scopes in sciences and technology put forward in Agenda 21st Century for each country. The Ministry of Land and Resources has started to deal with this project. The paper probes into the land use regions served to establish regional indicator system for sustainable land use, and displays notable divergences of different evaluation criteria of the grades of sustainable land use and diversity of indicator types within indicator system in different areas in China. Based on principles including relative identity between natural characters and land use conditions within an area, notable divergences in thresholds of main indicators or same indicators in different systems in different areas, and the integrity of administrative divisions, ten land use regions have carried out on the basis of comprehensive analysis of characters of land use patterns, environmental conditions, and management measures in different areas, and these ten land use regions are the regional scope for establishing regional indicator system for sustainable land use.
