摘要
长期以来湖北省各种土地类型的面积，尤其是耕地面积一直没有查清，土地利用规划没有一个真实可靠的数据可供依据。利用最近的三次土地调查资料和历年的统计资料，对湖北省土地资源的数量和现状进行了分析， 并利用1996年统一变更调查数据恢复重建了湖北省历年的实际耕地面积。结果表明，湖北省的实际耕地面积是统计年鉴中数字的1.4～1.5倍，但这并不意味着湖北省的耕地面积比原来增加了，实际所拥有和正在利用的耕地数量和生产能力与原来是一样的。由于水土流失和土地污染的加剧，优质耕地数量减少等原因，湖北省的土地质量总体呈下降的趋势。在土地资源的开发利用中，存在着结构不合理，效益未充分发挥，城乡居民点用地外延扩展过快等突出问题。展望了21世纪初期所面临的形势。结果可作为湖北省土地承载力的评价和土地利用规划的参考依据。
The actual areas of various types of land, especially cultivated land,in Hubei Province had long been indefinite. This paper analyzes the quantity and quality of land and situation of land use in Hubei Province based on data from the last three surveys and statistical yearbooks, and rebuilds the actual cultivated land area of Hubei in the past years according to the surveyed data in 1996. Result of this study shows that the actual area of cultivated land is generally 1.4～1.5 times of the data listed in statistical yearbooks, but this does not mean an increase in the area of the cultivated land the actual quantities and producing capabilities of the cultivated land remain the same as before. As a whole, the land quality of the province is descending because of the aggravation of soil erosion and land pollution, and the decrement of high quality cultivated land. There are also some serious problems of land use in this area. The land use is neither rational in structure nor adequate in profit. The land occupation of residential district expands too fast. At the end, the author looks forward to the situation of land resources, especially the cultivated land,in the early period of 21st Century. The data of the paper can be used as a basis for planning of land use and evaluation of land carrying capacity of Hubei Province.
