湟水流域是青海省经济、人口、文化重心 ,但频繁发生的灾害对流域乃至全省经济持续发展产生了消极影响。由于研究区域位于青藏高原向黄土高原的过渡地带 ,与全国其他地区相比 ,灾害在分布、发生特点、成因上不仅具有过渡特点 ,而且具有综合的特点 ,具体表现为种类繁多、垂直地带性特征显著 ,即随着地势高低 ,上下游地势显著变化 ,灾害在类型组合、发生强度、承灾体、致灾因子上都有显著不同 ,针对这些特点 ,提出了分流域段、分地势高低治理的对策。
The Huang shui River is the economic,populated and cultural centre of Qing Hai province But it is also an area frequently causing disasters, which makes negative influence on sustain development of the whole catchment and even the whole province Because the catchment is a transitional area between the Tibet plateau and The Huangtu plateau In contrast with the other areas in the whole country, the characteristic of occurrence and distribution of disasters not only is transitional, but also is synthetic It particularly displays actitudinal zonality that with terrain of mountain changing ,the type of constitution,intensity of occurrence , the beared object ,object causing disaster all of them have produced distinguished difference Aim at these characteristics, I put forward the opinion on controlling disasters in the Huangshui River catchment The main meaning of the opinion is that different way is used to harness different terrain or to harness different drain area which lies in different beach
