土地利用/覆被变化研究的实质分析与进展评述

作为当前研究的前沿领域，LUCC研究所涉及的研究内容不仅丰富而且繁杂。本文从LUCC研究计划的根本目标出发．指出LUCC所研究的诸多科学问题之间存在着紧密的联系，其实质是因果关系．而且LUCC研究可以简单明了地归纳为三个研究构成环节(LUCC原因、LUCC状况和LUCC结果)和四个核心研究内容(LUCC驱动力与驱动机制、LUCC状况、LUCC效应研究与作用机制、LUCC模型模拟与土地可持续利用)，文章针对此四个方面的研究进展进行了综述。此外．作者对LUCC的研究趋势进行了展望。指出：LUCC研究的主要趋势是走向综合，LUCC的环境效应研究与LUCC微观机理与过程的研究是当前LUCC研究的两个热点．而研究尺度的综合和模型构建是LUCC研究的两大难点问题。

An Essential Analysis and Review on Land Use/Cover Change Research

Although the research of Land Use/Cover Change (LUCC) involves many scientific issues, there exist some inherent relations. Based on the analysis to the fundamental goal of the LUCC Plan, the author points out that the essential relationship among those issues is causality. According to this relation, the research on LUCC can be simply divided into three components: reasons of LUCC, states of LUCC and results of LUCC, and four research aspects: drivers and mechanisms of LUCC, states of LUCC, effects and processes of LUCC and models and simulations of LUCC. After reviewing the current research situation of LUCC, this paper also puts forth several prospects on its future development: the whole trend will be synthesis, the environmental effect and the micro mechanism of LUCC are still the research hotspots, and the synthesis of scales and the establish of models will be the research difficulties.
