内蒙古赤峰市兴隆庄小流域,总面积40896亩。有490户,2082人,分居在7个自然屯。这里交通方便,地处矿区,有着发展村办企业及副业的便利条件。 在治理前,水土流失面积占总面积的96.4％,年土壤侵蚀模数5800吨/平方公里,旱、洪、虫、雹、霜等自然灾害不断发生,人均有粮食不过百公斤,人均收入不足50元。 一、试点期间开展的主要研究项目 1985年兴隆庄被列为内蒙古重点治理小流域后本着“巩固提高治理成果,调整措施配置方式,加快治理速度,提高治理标准,突出经济效益”的原则,进行了全面规划,制定了分年实施方案。 (一)调整原有措施配置 1.坡面措施的调整 在原有的小鱼鳞坑、小方坑和工程稀疏地段,根据暴雨设计标准,因地制宜加修水平沟、鱼鳞坑。按阴、阳坡和土质特点、分别补植油松、落叶松、杨树、山杏等树种,在工程
Xinglongzhuang small watershed in Chifeng City, Inner Mongolia, with a total area of 40,896 acres. There are 490 households, 2,082 people, separated in seven natural villages. Convenient transportation here, is located in the mining area, with the development of village-owned enterprises and sideline facilities. Before the treatment, the area of soil erosion accounted for 96.4% of the total area and the annual soil erosion modulus was 5800 tons per square kilometer. Natural disasters such as drought, flood, insect pest, hail and frost occurred constantly. Each person had less than 100 kilograms of food but insufficient per capita income 50 RMB. I. Main research projects carried out during the piloting period In 1985, Xinglongzhuang was listed as the principle of “strengthening the results of governance improvement, adjusting the allocation of measures, accelerating the speed of governance, raising the governance standards and highlighting the economic benefits” after being listed as the key watershed management in Inner Mongolia. Conducted a comprehensive plan and formulated a year-long implementation plan. (A) the adjustment of the original measures configuration 1. slope adjustment measures In the original small fish scale pit, small square pit and sparsely populated areas, according to stormwater design standards, according to local conditions to repair the horizontal ditch, fish scale pit. According to Yin, Yang slope and soil characteristics, respectively, Pinus tabulaeformis, larch, poplar, apricot and other tree species, in engineering
