为了建立区域土地可持续利用指标体系 ,必须透彻了解区域土地利用系统的结构、功能特点以及土地可持续利用的目标 ,准确反映不同区域土地可持续利用水平、诸多方面的的协调发展状况及其相互作用的结果信息。据此 ,本文选取相互独立且反映各方面特征的典型敏感指标 ,构建了包括目标层、准则层、因素层、元素层四个层次的土地可持续利用评价指标体系的结构框架。目标层从宏观层次刻划土地可持续利用系统作用规律 ,反映区域土地利用系统的总体状况。准则层是对评价目标的分解 ,是为了进一步表征区域土地利用系统中各部分对区域土地可持续利用的作用和影响 ,包括生产性、稳定性、保护性、经济活力、可接受性。因素层表征土地利用系统中每个方面的作用和影响 ,每个评价因素由若干评价元素具体表述。

In order to develop indicator system of regional land for land sustainable use, structures and functions of regional land use system, as well as objects of regional land for sustainable use, must be intensively understood; land sustainable use level, coordinative development and interactional status in different regions should be accurately reflected. Hereby, this paper selects typical sensitive indicators, which are independent and reflect the features in all aspects, to design the frame of indicator system of regional land for sustainable use, including object level, rule level, factor level and element level. The object level shows acting rule of land use system from the macroscopical level and reflects whole situation of regional land sustainable use. The rule level is the disintegration of the object level, and ulteriorly declare the act and impact of each aspects in land use system for regional land sustainable use, including productivity, protection, security, viability and acceptability. The factor level clues in the act and impact of every part in land use system, and every evaluated factor is concretely delivered by some elements. The element level is the smallest unit of this indicator system, and as the basic indicator describing evaluated factors, is the concrete measurement of sustainable land use degree in this indicator system.
