摘要
数据统计分析表明,湖北省坡耕地(坡度在15°以上)面积为934867.2hm2,占全省耕地总面积的18.99%,高于全国平均水平。从区域分布来看,湖北省四分之三以上的坡耕地分布在鄂西山区,其中80%以上的≥25°坡耕地也分布在鄂西山区。因此,从生态适应性及生态建设紧迫性来看,湖北省生态退耕应以三峡库区及清江流域为重点,突出对我省"两江两库"等生态地位重要地区以及其它局部陡坡耕地和严重沙化耕地的重点治理。
According to the analysis of data statistic, the sloping cultivated land area( the gradient 〉15°) in Hubei Province is 934 867.2 hm^2and occupies 18.99 % area of the whole agricultural acreage, and better than the average .As the distribution, above 3/4 of the sloping cultivated area lies in the western of Hubei Province, also above 80% of such land with the gradient 〉25°onsequently, in terms of the adaptability and urgency of ecology construction, the Three Gorges and the Qingjiang River catchments must be considered as the key distinctions. It gives prominent to the "two rivers and two reservoirs" which is the important areas in the ecological administer, and the main administer of other part of steep sloping cultivated land and desertification farmland.
