我国南方低丘红壤荒地面积总计1.1亿多亩,约占全国荒地资源的1/6。江西省竟占有1200万亩。这些区域光、热、水和生物等自然资源十分丰富。但由于受季节性干旱威胁的面积达100％,具有不同程度水土流失的面积占50％,多数土壤肥力衰竭。这样,不仅限制了资源潜力的充分利用。而且酿成区域性环境治理的严重问题。所以,本文即以在自然和社会生产力条件等方面都有代表性的江西省临川县小华山试验区为对象,对它们作了土地及自然资源的详查、分析评价与治理利用设计,借以对剖析低丘红壤的改造提供科学依据。
China’s southern hilly red soil wasteland totaling 110 million mu of land, accounting for about 1/6 of the country’s wasteland resources. Jiangxi actually occupy 12 million mu. Natural resources such as light, heat, water and biology are abundant in these areas. However, due to the seasonal drought-threatening area of 100%, with varying degrees of soil erosion accounted for 50% of the area, the majority of soil fertility failure. In this way, not only limited the full utilization of resource potential. But also lead to a serious problem of regional environmental governance. Therefore, this article aims at the Xiaoshan Experimental Zone of Linchuan County in Jiangxi Province, which is representative of the natural and social productive forces conditions, and makes a detailed survey of the land and natural resources, analyzes and evaluates the management and utilization design of the natural resources, Provide a scientific basis for analyzing the transformation of hilly red soil.
