中文摘要	1979-1984年，结合四川省和云南省的委托任务，与当地政府一起，开展了川西滇北山区泥石流综合治理研究，选择了对铁路、城镇和农业危害严重的四川凉山黑沙河、南坪县后山、雅安市陆王沟干溪沟、喜德县东沟、汉源县狮子沟、云南盈江县浑水沟、东川市大桥河、梁河县三家沟永安寨沟等八处典型泥石流作为试点，进行综合治理。本文介绍了川西滇北山区泥石流防治方案及措施，治理效益和体会。
英文摘要	With suitable environment to forming and bursting debris flow,the mountainous region in West Sichuan and North Yunnan is one of the most developed debris flow regions in China.There are debris flows in 192 counties, ard 49 county cities are damaged or seriously threatened by debris flows in every rainy season and many of agriculture, industry and other projects often suffer heavy debris flow disaster in the region.To solve the problem, the Debris Flow Research Division of Chengdu Institute of Geography with local unities has conducted the experiment on comprehensive curing debris flows at 8 selected typical places in the region.Debris flow in the region are mainly caused by rainstorm. Accord- ing to the resource of loose earth and distribution of generating zone, they may be chiefly divided into two types:One of them is the debris flow with complex generation. The loose earth in it is supplied from various ways, such as landslides,collapses, eroded slope and riverbed, and the areas of its generating zone, with extensive scatter, is greater.Another one is simplex debris flow. The loose earth in it is chiefly supplied from one way and its generating zone is more centralized.The debris flow disaster is made from various factors of the natural environment and human activities. In different regions, the difference of nature conditions is very great and economic and social situations are different from one to another. Curing the debris flow disaster, these practical cases should be seriously considered and various corresponding schemes to them are practised respectively. The 8 selected places are divided into 3 types of schemes for curing:1.Comprehensive cure for whole basin. This type is often practised in cases of curing debris flows with complex generation, guarding more importatnt projects, demanding higher surety and having enough fund. The comprehensive cure for debris flows at Heisha River and Houshan of Nanping County of Sichuan Province, and Daqiao River of Yunnan Province belongs to the type.2.Comprehensive cure emphasized in stopping and checking measures. This type is often suitable for controlling simplex or compound debris flows, with a good landform for building a dam to stop and stabilize the loose carth in gullies, aiming at reducing sediment into chief river, avoiding damage from debris flows. The comprehensive cure for debris flows at Huenshui Gully of Yingjiang County, Shanjiacen and Yungan-zhai Gullies of Lianghe County of Yunnan Province, and Sizhi Gully of Hanyuan County, Sichuan Province belongs to the type.3. Comprehensive cure combined by stopping with draining means and stressed in either stopping or draining. The type is often used under landform suitable for draining debris flows but unsuitable for building a dam, aimed at preventing guarded projects from being damaged. At Luwang and Ganxi Gullies of Yaan City, and Dong Gully of Xide County, Sichuan Province, this type has been adopted.The design of various measures mentioned above has all considered characteristics of debris flows Above experiments on comprehensive cure for eight selected places adopted various measures totaled up 397 items, costed more than 8 million yuan (about $ 3 million), had been successively completed during years 1979-1984. The aim of comprehensive cure has reached and the debris flow disaster at selected places has been controlled. It has been proved that they are achievable through examination more times of rainstrom or heavy rainstorm. The gained economic value is more then 20-fold of curing cost. Not only controlling disaster but achieving profit, the waste debris flow fan in the lower has been become good arable,vegetative cover has been better recovered, biological environment has been apparently improved, all of these have produced better social and political effect.
