摘　　要：自然资源指标主要用于对各类自然资源进行定性或定量评估。目前,自然资源指标研究主要是相应领域的指标体系建立,但自然资源指标动态更新机制的研究甚少。自然资源数据具有多源异构、规模大、更新频率高的特点,指标的动态更新难度也较大。本文基于统一的国土空间基础信息平台,建立了一个灵活的指标模型构建器,通过构建各类指标计算模型,实现时间维度和空间维度的自然资源指标动态更新,为自然资源指标动态更新提供一种有效的技术途径。Indicators of natural resources are mainly used for qualitative or quantitative assessment of various natural resources.There are a lot of studies on how to establish an indicator system for development and planning of natural resources,but few on how to realize dynamic update for natural resources'indicators.Natural resources data is multisource heterogeneous,large-scale and has high frequency of updating,so that it is difficult to achieve the dynamic update of indicators.Based on the consistent land space information platform,this paper develops a model-builder for indicators to define kinds of calculation model which are used to calculate natural resources'indicators over time dimension and space dimension and provides an effective technology method for dynamic update of indicators for natural resources.
