摘　　要：从口门稳定性的角度,分析了三大人为工程(太阳河改道、在通道口修筑北堤和封堵南汊道及约5 km2的潮滩被围垦)所起的作用以及波浪动力对小海口门演变的影响,认为小海潟湖潮汐通道在其演变进程中,由于潮汐弱而波能相对较强,目前仍属波浪作用为主型,依据自己多年的研究工作,首次提出以口门复式断面和通道分汊的方法对小海及该类型潟湖进行治理。In Xiaohai lagoon of Hainan Province from 1972 to 1986, a large-scale project was made for three times： changing the course of Taiyang River, building the northern dyke at inlet mouth, and blocking the southern branch of inlet as well as enclosing 5 km^2 tideland. That resulted in the tide range of lagoon getting smaller （from 0.7 m to 0.2 m）, while the inlet mouth width getting narrower （from 150 m to 30 m） and causing serious inundation in 2000 year. The effects of these projects and wave on the inlet revolution of Xiaohai lagoon are analyzed. The measures to transform the lagoon, double profile and inlet dividing are put forward.
