A survey was developed to a representative sample of Huaihe River Basin inhabitants to study the effect of water pollution control policy,including the water quality,ecological state of Huaihe River,the pollution impact on inhabitants' daily life and agriculture,fishery,and the water pollutants discharged to Huaihe River. Through the survey,the paper finds: Huaihe River is largely suitable for irrigation usage while a proportion of 1/3 of it is suitable for swimming; nearly 40% of the interviewees express unsatisfaction on Huaihe River's water quality; the ecological state degraded in evaluation period with an obviously decrease on aquatic life amount; water pollution,especially unpreviewed water quality decline causes fishery industry loss and the famous Hongzehu Lake fishery downstream Huaihe River suffered great loss from it; 1/3 of the interviewees hold that the sewage discharged from outlets along Huaihe River is always unclean and smelly while another 50% of them think the discharge is unstable in colour and smell; among all types of wastewater discharge,industry discharge is worst with 80% interviewees blame it is abnormal in colour and smell. The questionnaire also assesses the environmental information disclosure in Huaihe River Basion,which implies: disclosure has positive impacts on rising inhabitants understanding on water environment,but they still want to acquire more information on water pollution,water quality and pollution control actions. <<
