白水地处渭北旱原,地形复杂,沟壑总面积502.99平方公里,占全县总面积的52%。25°以上的坡耕地1万多公顷,荒山总面积15万公顷,尚有宜林荒山0.9万公顷。以原面水蚀为主的水土流失约8.4万多公顷,占总面积91.6%,年侵蚀模数为3935—4294吨/平方公里,系层次强度水土流失区,属暖温带大陆季风气候。该区光照充足,雨量较多,适宜多种树木的生长。省、地曾先后将我县列为“三北”防护林建设,黄河中游水土保持基地县之一。建国后,林业虽有较大的发展,但由于缺乏用生态经济学观点指导林业生产,加之工作中的失误,致使该县依然存在着生态恶化问题。通过实践认识,我
White water is located in Weibei drylands, terrain, gully total area of 502.99 square kilometers, accounting for 52% of the total area of the county. Over 25 hectares of slope farmland more than 10,000 hectares, a total area of 150,000 hectares of barren hills, there are still 19,000 hectares of barren hills. Water erosion of the main surface water erosion of about 84,000 hectares, accounting for a total area of 91.6%, annual erosion modulus of 3935-4294 tons / square kilometers, the Department of the level of intensity of soil erosion area, is a warm temperate continental monsoon climate. The area is full of light, rainfall is more suitable for a variety of tree growth. The province and the land successively listed our county as one of the “Three Norths” shelterbelt construction counties and one of the counties in the middle reaches of the Yellow River as a water and soil conservation base. After the founding of the People’s Republic of China, despite the great development of forestry, due to the lack of directing forestry production from the viewpoint of ecological economics and the mistakes made in its work, the ecological deterioration of the county still exists. Through practice, I
