基于多维尺度分析的土地科学决策支持系统研究现状分析

研究目的：分析国内近16年土地科学决策支持系统研究动态，探讨其发展趋势。研究方法：共词聚类分析法和多维尺度分析法。研究结果：通过分析土地科学决策支持系统的相关文献，土地科学决策支持系统可分为土地利用规划决策支持系统、土地空间决策支持系统、土地评价决策支持系统、土地生态安全决策支持系统以及其他土地管理决策支持系统5种类型，并对其研究现状和发展趋势进行了分析。研究结论：（1）土地利用规划决策支持系统目前国内研究较多，关注度较高。其他方向还有待进一步研究。（2）随着3S、专家系统、数据挖掘等技术的不断发展，决策支持系统得到不断的完善和发展，一些新的技术和理论方法将被引入决策支持系统。土地科学决策支持系统将向集成化、智能化、网络化及可视化方向发展。

Current Status of Land Science Decision Support System Based on Multi-dimension Analysis

The purpose of this paper is to analyze the current status and the trend of land science decision support system（LSDSS） in China in the past 16 years. Method of co-term clustering analysis and multi-dimension analysis were employed. The results show that LSDSS can be classified into 5 types according to the literature review, namely land use planning decision support system, land-spatial decision support system, land evaluation decision support system, land ecological security decision support system, and other land management decision support system. The current status and the trend were also analyzed. The conclusions are as follows:（1）decision support system of land use planning is widely studied domestically, but research in other fields needs more attention and efforts;（2）with the development of  technology, such as 3S, expert system, and data mining, the decision support system has been continually improved and developed. Meanwhile some new techniques and theoretical methods are also being introduced into decision support system. Thus land science decision support system will be developed in the direction of integration, intellectualization, networking, and visualization in the future.
