摘要
对中国北方农牧交错带土地沙漠化的现状、成因及防治技术等问题进行分析 ,指出北方农牧交错带是中国沙漠化发展最快、生态环境最脆弱的地区之一 ,其根本原因在于樵采、过牧、滥垦等人为活动过度。提出农牧交错带防治沙漠化的三大技术体系 ,即沙地植被恢复与固沙技术体系。
The status, causes and techniques for prevention of land desertification in the interlock zone of farming and pasturing of north China (IZFPNC) are analyzed. The results show that the IZFPNC has become one of areas where the speed of land desertification is most quick and ecological environment is most fragile in China. The fundamental causes of which lie in human activities such as over felling, excessive grazing and expende reclamation and so on. The technical systems for prevention of land desertification in the IZFPNC including technical systems of sandy vegetation restoration and sand fixation, technical systems of entensive agriculture & husbandary and technical systems of regional agricultural superiority resources development and sand industry.\;
