| 摘 要： | 沙漠-黄土边界带生态环境脆弱,对气候变化和人类活动反应敏感。近10年来,榆林地区由于重视沙漠化的防治工作,沙漠化出现逆转态势,但是其潜在威胁不容忽视。水蚀荒漠化状况依然比较严重。应当进行积极有效的防治。荒漠化是一个自然过程。荒漠化加速发展是在脆弱的生态环境基础上,由于人类不合理的土地和水资源利用方式而诱发的。应当处理好人口、资源和环境三者之间的关系,走社会经济可持续发展之路。 |
| 关 键 词： | 沙漠-黄土边界带 榆林地区 沙质荒漠化 水蚀荒漠化 成因分析 |

| Abstract: | Because of brittle environment, desert-loess boundary belt is sensitive about climate changes and human activities. In the past ten years, the trend of sandy desertification in Yulin area has reversed due to the emphasis on the prevention and control of sandy desertification. However, the potential treat to this area can not be neglected. Conditions of water-erosion desertification are rather serious there. This problem should be tackled actively and effectively. Desertification is a natural course. It is because of the brittle ecological environment together with the irrational way of using the water and land resources that caused the condition of desertification to worsen. Therefore, the relationship between human beings, resources and environment should be reasonably handled, so as to achieve a sustainable development in society and economy. |
