陕西省生态农业干旱区划研究   总被引:9,自引:2,他引:7  
选取主要气候变量、地质土壤类型、水文、径流特征、地表植被类型及分布等10个影响陕西省生态农业干旱因子,利用K-Means Clustel‘Analysis(快速聚类法)和Hierarchical Cluster Analy-sis(分层聚类法)相结合的方法,对陕西省生态农业干旱区划进行研究,将陕西地区划分为8个生态农业干旱相似区,并对区划合理性进行了检验.分析表明:采用生态因子和干旱因子相结合的聚类分析方法能够较好地反映陕西省生态农业干旱实际情况,充分地体现"陕西省生态农业干旱"的空间分布特征,具有较强的科学性.  相似文献

在干旱区,水是形成绿洲的根本要素。干旱区高寒山地是维系西北干旱区绿洲存在、是当地国民经济持续发展和生态环境稳定的水源地,山地森林生态系统具有重要的涵养水源功能,有“绿色水库”之称。气候变化将改变山地生态系统结构、组成和水循环,加剧水资源短缺,威胁干旱区绿洲安全。回顾并综述了干旱区气候变化及其对干旱区山地森林生态系统稳定性和水文过程的影响研究进展,指出了研究中存在的问题,并提出未来在干旱区山地仍需要评估优于1 km空间分辨率的气候变化趋势,从多尺度、多界面、多学科、多方法开展气候变化对干旱区山地森林生态系统稳定性和水文过程影响的综合研究,以促进干旱区山地生态学的发展,为干旱区管理部门提供适应和缓解气候变化、科学的制定气候变化条件下水资源管理方案、实现水资源的有效管理奠定理论基础,促进干旱区气候变化条件下的环境和社会经济可持续性发展。  相似文献

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world's largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.  相似文献
