摘要
广东省德庆县花岗岩分布面积占全县总面积的６７．３％ ，由于人为、自然因素影响，使该县成为广东省崩岗侵蚀最为严重的县之一。对于崩岗的治理，主要是根据崩岗的成因、类型和特点，采取工程和生物措施互补的综合治理方案。该县通过长期治理，已取得了显著的的生态、经济和社会效益，但水土流失（尤其是崩岗）仍很严重，治理任务还很艰巨，必须坚持下去。
The area of granite occupies 67.3% of total land area in Deqing county of Guangdong province. Due to artificialand naturalfactors, this county has the m ostseriousdisintegration in Guangdong province. Based on the contributing factors, types and featuresof the disintegration, the guiding principles of disintegration control are to apply thecoordination of engineering and biologicalm easures, w hich is to use engineering techniquesto arrest the im m ediate loss of soil, and to develop re vegetation program s for long termstabilization ofthe slopes. Greatbenefitsofsociety, ecology and econom y have been attainedafter ithas been controlled since 1949, butthe soilerosion (especially disintegration) is stillvery serious. Therefore, itm ustbe controlled perm anently. Atthe sam etim e, som e feasibleproposals are presented for its controlling.
