摘　　要：选择13个资源环境因子进行土地利用的资源环境区划,将湖北省划分为平原区、丘陵区、山地区等3类区域;从生态、经济、社会三方面对区域土地利用系统的现状加以评价,并分析了存在的主要问题;提出了区域土地可持续利用模式.当前湖北土地利用存在的问题主要包括水旱灾害加重、水土流失与土地污染较严重、产出不太稳定、经济效益不高、土地利用结构太偏重种植业、耕地逐年减少等等.为实现区域土地可持续利用,应从将区域土地利用作为一个大型复合系统的观点出发,根据系统的结构和功能,调整系统内部的物质、能量和信息流,其关键是土地利用结构调整.In this paper, at first, 13 factors of resource and environment are chosen to carry on land use regionalization of resource and environment. The whole province is divided into 3 kinds of regions including plain area, hill area, mountainous area. And then status quo of regional land use system is evaluated from 3 respects including ecology, economy, society. And the main existent problems of land use system are analyzed. Finally, regional model of sustainable landuse is put forward. At present, the existent problems of landuse in Hubei province include mainly flooding and drought being aggravated, soil erosion and land pollution being more serious, agricultural output being un stable enough, economic benefits being not high, landuse structure laying too particular stress on planting, farmland area reducing year by year etc. In order to carry out regional land sustainable use, people should start from a point of view regarding land use as a large compound ecosystem, and according to structure and functions of the system, adjust matter, energy, information flow in inner system. The key is to adjust landuse structure.
