摘要:
近年来，由于受气候、土壤、植被等自然因素和人为因素的影响，我国干旱、半干旱区草场沙退化现象十分严重，草原生态环境日益恶化，严重制约了牧区经济的可持续发展。针对干旱、半干旱区草场沙退化的形成过程和特点，采用主成分分析（PCA）的方法，从影响草场沙退化的自然因素和人为因素中选出若干因子，以锡林郭勒盟正镶白旗明安图镇东部和硕庙的数据为基础，分析了影响该地区草场沙退化的主要因子，从而为全面整治草场沙退化提供科学依据，这必将对我国国土资源的保护与开发、改善区域生态环境具有重要意义。
Abstract:
In recent years,because of the influence of natural factors such as humid,soil and vegetation and factitious factors,grasslands desertization and desertification is very serious and the grassland eco-environment deteriorates increasingly,which badly restricts the sustainable development of pasturing area economy.Aiming at the forming process and characteristics of grasslands desertization and desertification in arid and semi-arid areas,using the method of principal component analysis,selecting some factors from natural factors and factitious factors which influence grasslands desertization and desertification,based on the test dada in Heshuo temple of Mingantu town of Zhengxiangbai white Banner in Xilinguole League,the main factors influencing grasslands desertization and desertification in this region are analyzed.It has scientific significance for renovating grasslands desertization and desertification.
