中国西部土地荒漠化问题探索

The Probe on the Desertification of the Western Regions in China

中国西部地区土地荒漠化问题相当严重。采用多学科交叉的方法,从宏观、中观、微观诸方面考察了西部地区土地荒漠化的演变过程及其时空特征。研究结果表明:西部土地荒漠化问题是在漫长的历史岁月中逐渐形成的,并且呈现出逐渐加剧的态势;导致土地荒漠化的因素包括自然和社会两个方面,近五千年来人为因素的影响力往往超过了自然因素。人类不良的生产生活方式会大大加速土地荒漠化的进程,而科学的土地开发及合理的环保措施则能对土地荒漠化起到扼制、延缓、逆转的作用。

The desertification of the western regions in China is quite serious. This paper examines the evolution and the characteristics of time and space of the desertification of the western regions in China from the marco-, medium-and micro-view point by means of multidisciplinary intersection. The findings show that the desertification of the western regions has been formed gradually in the past historical stages and the situation has gradually worsened. The factors of the desertification includes such two aspects of nature and society, whereas the influence of human powers usually surpasses that of natural factors. The human beings, inedequate mode of production and living will accelerate the process of the desertification, while the scientific land development and rational environmental protection will play an important role of depression, retaining and reversion towards the desertification.
