As a new-replacement of energy resource, coal bed methane is the important gas resource with great strategic significance. There are several number of Mesozoic coal-bearing basins in Jiamusi landmass, eastern Heilongjiang Province. Theresult of the resource assessment revealed that the total resource less than 1 500 m,s depth in the area is about 2 100×108m3. It shows that Jiamusi landmass has great potential of coal-bed gas and is one of the most prospecting districts for developing coal-bed gas in CBM-province Northeast china.

The present paper is based on the results of experiments on the adsorption of sulfide of bottom soil, which were carried out in 1979-1981, and gives special emphasis on the problem of the occurrence of the harm caused by hydrogen sulfide (H2S) to the shrimps cultured in the high-production earthen pond. The scientific basis of prevention and control of the harm caused by hydrogen sulfide occurring in the pond and a simple effective measure for high, stable production of penaeid shrimp culture are proposed accordingly.
