摘要:
陕北黄土高原属于干旱半干旱地区，由风沙区、丘陵沟壑区和高原沟壑区三大类型区组成。区内土壤侵蚀和土地沙化严重，生态环境极为脆弱，严重影响着区域社会经济的发展。经过40多年的综合治理，局部地区水土流失与土地沙化得到有效治理，生态环境和农业生产条件明显改善，产业结构得到调整，粮食生产显著提高，农村经济迅速发展。表明通过开展以水土保持为中心的综合治理，生态环境可以得到根本改观，能够实现可持续发展。但整体上生态环境恶化的趋势还没有从根本上扭转，环境建设仍然是一项长期而艰巨的任务。根据当地生态环境条件和几十年生态环境
Abstract:
The Loess Plateau of the northern part of Shaanxi Province, located in arid and semi-arid region, consists of wind-sand area, gully-hilly area and high plain and deep gully area. Severe soil erosion, land desertification and fragile eco-environment severely restrict local social-economic development. Through comprehensive harnessing of soil and water conservation for over 40 years, soil and water loss and land desertification in certain region have been controlled, eco-environment has changed better, which makes agricultural production conditions improve, grain production increase, countryside economy develop speedily. The above mentioned accomplishments prove that through comprehensive harnessing of soil and water conservation, eco-environment can be thoroughly improved and sustainable development may be realized. However, the worsening trend of eco-environment of whole region has not been reversed yet. Therefore, eco-environment construction is still an arduous task for a long time. According to local eco-environmental conditions and experiences and lessons in eco-environmental construction for over several decades, local eco-environmental construction should take environmental improvement as a basis, strengthen construction of eco-agriculture with soil and water conservation and realize regional sustainable development. In the rebuilding eco-environment, productive farmland construction is a base, planting trees and bushes and growing grasses are key measures to improve eco-environment. Dryland farming techniques of increasing crop yield, techniques ofwater harvest and water-saving should be greatly spread to use rainfall resources fully and efficiently.
