    摘要:

    陕南秦巴山区大小川道,是当地的精华,群众长期来埋头在川道束水造田,取得了很大成绩。但不少川道仍然摆脱不了洪水毁灭性灾害,有的已经反复冲修若干次,有的已被泥沙吞没。山上坡陡耕地少,而且面积逐年下降,地力减退,几十年来陕南人均耕地由0.20hm2多下降到670m2多,不少县已不足670m2。为了保护基本农田和延长川道利用寿命达到可持续发展,本文通过大量调查研究,分析了产生灾害的原因,提出了川道治理的新思路。

    Abstract:

    There are a lot of vast and narrow plain in the Qin-Ba mountain area of South Shaanxi Province, which is regarded as the essential things. For a long time, local people have worked hard to build their farm land by reconstructing the bank and have acquired great achievements. However much plain can not still get rid of flood rushing calamity, and some have been rushed and repaired once and again; others have been submerged under the mud and sand. Slope and steep land of the mountains is increasing decreased and the soil fertility drops year by year, during tens of years, the average farmland per people of South Shaanxi Province has dropped from more than 0.2 hm2 to 0.067 hm2, what is more, it has dropped to little than 670 m2 in some counties. To protect the basic agriculture land, prolong the usable life of plains in the river, and keep a sustained development, based on a great number of investigation, this article investigated and analyzed the reason of the producing calamity, and then put forward a very good suggestion about repair plains in the river.
