【摘要】 根据安徽省生态环境现状调查的结果 ,耕地是安徽省主要的土地利用类型。由于经济建设、生态建设、经济利益的驱动和有限的后备资源 ,耕地面积逐年减少 ;肥力不足、土壤退化、水土流失等因素影响了安徽省耕地资源质量 ;低的生态占用表明该省人口数量已给环境造成巨大的生态压力 ,人地矛盾日趋突出。粮食的安全保障依赖于耕地的高强度利用、化肥的大量施用和有效灌溉面积的扩大。加强土地管理 ,严格执法 ,合理规划用地 ,以科学技术来提高粮食的单产水平和土地利用的集约化程度 ,是耕地可持续利用的保证。更多还原

【Abstract】 Based on the results of the survey of the current situation of ecological environment in Anhui Province,cultivated land is the main type of land use.As a result of economic construction,ecological construction,economic benefit driven activities and limited back-up resource,the acreage of cultivated land is decreasing year by year.Insufficient nutrient supply,land degradation,soil erosion and some other factors affect the quality of the cultivated land.The lower ecological footprint shows that the increasing population has been causing an enormous ecological pressure to the environment.The conflict between the men and land is getting more and more prominent.Guarantee of food supply depends more and more on highly intensive utilization of the cultivated land,increased application rate of chemical fertilizers and expansion of the effectively irrigated area.However,the guarantee of sustainable utilization of the cultivated land is to intensify land management,strictly enforce the land related laws and regulations,proper plan for land use,increase the grain yield per unit area and the degree of land use intensity with the aid of science and technology.更多还原
