摘要
以宁夏南部山区固原市原州区为研究对象,根据区域的自然环境和人文特点,在对以往退耕还林还草工程实施经验的总结与借鉴的基础上,认为退耕还林还草工程的实施必须要遵循“生态优先”和“科学性”的原则,要从工程措施和保障措施两方面入手。首先确定了原州区三个重点退耕区六盘山外围退耕区、原州区东北部干旱带退耕区、固原市区外围“五山两河”绿化区,然后根据区域不同的立地条件,科学的选择适宜本地的树种、草种,制定了林草配置比例和模式以及相应地技术措施。只有将工程措施与保障措施相互配合,相互协调,才能使得区域生态环境与人民脱贫致富达到“双赢”,保证本区域实现生态、经济和社会的可持续发展。
Yuanzhou district of Guyuan in the south of Ningxia was taken as a research object,according to the analysis of natural environment and culture of this region and based on the experience of converting cropland to forest and grassland,it is considered that the implementation of this project must follow two principles “ecology ”and “science”,and two aspects:project measure and ensuring measure.First,make three emphasis areas:the area of periphery of Liupan mountain,the drought area in the east and north of Yuanzhou region,drainage area of Qingshui River in the north of Guyuan town.Then according to different natural conditions,such as moisture,soil,landform,etc.to choose suitable trees and grass,arrange the proportion of arbor,frutex and grass,and take corresponding technology measure.Only by this two measures cooperating and harmonizing with each other primely,can the ecology environment in this region be improved so as to ensure the sustainable development of ecology,economy and society in this region.
