| Research Abstract |
The northeastern part of China is very cold and few in precipitation , especially in winter . There are two big rivers : Heilogjiang River and Songhaujiang River . Under Quick economic developments , problems on water , snow and ice have occurred in this region . In this circumstances , a joint project was carried out on water environments and the following results were obtained:
At Xinlin in Daxinganling region , automatic recorders of river water level , precipitation and air temperature set up and some important hydrologic date were obtained near Huma River , a branch of Heilogjiang River.
Hydrologic features are as follows : main runoff from April to September are due to precipitation and not to snow melting . High water level was recorded in summer of 1998 , when extraordinary floods occurred in Songhaujiang River .
Snow accumulation in winter is very low as compared with that in Japan . Chemical characteristics in precipitation at Xinlin are different from that of Nagaoka.
Form the analysis of or ganohalides in tap water , the quality level at Harbin City is under reference level in Japan .
A few of hydrological and meteorological date were collected in Xinlin area , but it has been more difficult to continue to collect such date because there exists many politic and economic problems in China.
