In order to reveal the relationship between the geo-environment, especially drinking water, and the disease, the senior author has made an investigation on the pathogeny and epidemiology of the disease and some characteristics of drinking water, including the source, chemical composition and radioactivity of all kinds of drinking water (river water, spring water, running water). We adopted a routine method to analyze major ions and the atom spectra of the minor elements. At the same time, we made similar investigations in Muyu Town for comparison. The results showed that all the indices of surface water & ground water in the two towns have not gone beyond 《Water Quality Standards for Drinking Water Source》 (CJ3020-93) and that the radioactivity (γ-ray) of the water from Songbai Town is higher than that of the water from Muyu Town, but the incidence of the disease is higher than that in Muyu Town. So, it can be concluded that there is no direct relationship between the disease and the hydro-environment.展开更多

It also proposed the construction of stable ecological green space pattern of towns, the development of forest-type green space and the planning ideas of green space system in small towns that can embody regional context and implement multifunctional composite.展开更多
