建瓯县位于闽北山区,长期以来由于利用土地资源要求不严,虽经几年的综合治理收到一定成效,但未从根本上制止水土流失,且存在着边治理边破坏的现象。1983年普查时,全县水土流失面积29220公顷,其中强度流失8173公顷,占28％。三年来流失程度在加剧,强度流失面积上升到32％,茶果园和坡耕地的水土流失面积增加了17％,同时,开矿修路和一些基本建设单位,任意倾倒矿渣废土石的现象仍较普遍。针对这种情况,根据我县水土流失地类集中的特点,必须“以防为主”搞好水土保持,应从以下几方面着手: 一、山地面积大,森林资源丰富,抓好林业生产上的防治。(一)充分发挥森林效益,提高对森
Jian’ou County is located in the mountainous region of northern Fujian. For a long time, due to the lax requirements of utilizing land resources, although some achievements have been made in the comprehensive management over several years, it has not fundamentally stopped the soil and water loss and ruined the environment. In the 1983 census, the area of soil and water loss in the county was 29,220 hectares, of which 8,173 hectares were lost in intensity, accounting for 28%. In the past three years, the degree of loss has been aggravating, the area of intensity loss has risen to 32%, and the area of soil erosion in tea orchards and sloping fields has increased by 17%. Meanwhile, mining and road construction and some capital construction units have been dumping slag and rock waste more generally . In view of this situation, according to the characteristics of the concentration of soil and water loss in our county, we must do well in prevention and control of soil and water conservation. We should proceed from the following aspects: First, large mountainous area, rich forest resources, good forestry production Prevention and treatment. (A) give full play to the effectiveness of forests, improve the Sen
