比重

The proportion of reserves of low permeability gas reservoirs to nonproducing reserves is larger and larger in China at present. And the depletion way of production is used in low permeability gas reservoir currently, so the gradual drop of formation pressure during the exploitation will result in the deformation of rocks, which makes the reservoir porosity and permeability decline.

目前中国低渗透气藏的储量占未动用气藏储量的比重越来越大，而低渗透气藏一般都采用衰竭式开采，在生产过程中地层压力逐渐下降，导致储层岩石变形，使得孔隙度和渗透率降低，从而导致低渗透气藏开发效果变差。

Here, we took demonstration study of the ecological impacts of disconnection from the river on fish recources in Zhangdu Lake. Our results showed that:(1) Fishery mode changed and the rate of wild fishery production changed from 95% in 1949 to less than 5% in 2002.(2) Fish species have decreased from 80 in 1950s to 52 at present, and the rate of migrant and potamic species decreased from 50% in 1950s to 30% at present.

我们以涨渡湖为例开展江湖阻隔后对单个湖泊鱼类资源所产生的生态影响进行研究，结果表明：江湖阻隔导致湖泊生产经营方式改变，使得野生渔业产量的比例由1949年的95%，降低到2002年的不足5%；江湖阻隔后湖泊鱼类种类由50年代约80种下降到现在的52种，其中，洄游性和流水型鱼类比重由50%下降至不足30
