摘要: 荒漠化是全球严重的环境问题之一,沙漠化是干旱、半干旱及部分半湿润地区由于人地关系不协调所造成的以风沙活动为主要标志的土地退化。甘肃省地处大陆腹地,沙漠化危害严重。通过建立沙漠化土地封禁保护区,能够促进保护区植被的恢复和生态重建,增加生物多样性,遏制沙漠化土地扩展。根据《中华人民共和国防沙治沙法》要求,全省共建成七大省级沙漠化土地封禁保护区,按照一定的原则,目标和步骤逐步实施。由于各地自然条件的差异性与复杂性,防沙治沙的措施与手段各有特点,在具体的防沙治沙措施中,不能局限于一种措施、一种模式,需要综合考虑,运用最适合当地的思路、方式和方法来治理沙害。

Abstract: Desertification is one of the serious global environmental problems, and sandy desertification is land degradation characterized by wind erosion mainly resulted from the in-coordination between human impact and natural conditions in the arid, semiarid and some sub-humid regions. Gansu province lies in the interior of the continent and its desertification disaster is very severe which can be alleviated by the construction of the enclosure-conservation region of desertified land, the construction of enclosure-conservation region can improve the bio-diversity and promote the rehabilitation of the environment. So it is an effective method to control desertification in the arid area. In the light of the cause of sandy desertification extension and the problem in control, the desertified land in Gansu province can be classified as seven enclosure-conservation regions. Because of the difference and complexity of the natural conditions in different regions, accordingly distinct method should be used based on local conditions.

Key words: sandy desertification, enclosure-conservation region, methodology
