摘要
为了研究宁夏盐池县生态环境治理和保护对策,分析了人口增长过快,土地超载、沙化,人口与资源、环境的关系趋于紧张的主要原因———土地沙漠化、水土流失、干旱和其他自然灾害.目前,盐池县土地沙化面积已占全县土地面积的48.6%左右,草场面积仅有46×104hm 2,鲜草产量为185kg/hm 2,载畜能力为0.92hm 2养一只羊.该县生态环境的治理与保护的关键是调整土地结构、退耕还林还草、严格控制人口增长和提高人口素质,并且要有效保护和合理开发利用水资源.
In order to study the improvement of and the ideas of protection in Yanchi, this paper analysed the increasing population and land overload, the increasing relation of population and environment and resources. The main causes were: grassland degeneration, erosion, drought and other natural disasters. 48.6 percent of the whole area in Yanchi County was the desertification land. The area of grassland was only 46 × 10^4 hm^2, the yield of wet grass was 185 kg/hm^2, the grazing capacity was a sheep in 0. 92 hm^2. The principal task of improvement and protection is to adjust land construction, shift grain to greenland, control the increasing of population, improve the quality of population, and therefore, to efficiently protect and rationally exploit water resources.
