Need to prove that in addition the water in river is mobile, water ecological setting changes very frequent, and very big to the impact of biotic population in the water body, its catchment area is very big, so pollution of area source is very big, also receives the influence of point-source pollution more easily.And the lake is for the river, and the water surface is big, storage capacity is big, water body environment is stable, it is very little to flow, and its catchment area is also less, so the pollution of area source in lake and point-source pollution are less relatively, water body environment is comparatively stable, also is easier to improvement.Therefore, the river is different with the improvement in lake.
Should be noted that at last; Above embodiment is only in order to technical scheme of the present invention to be described but not to the restriction of protection domain of the present invention; Although the present invention has been done detailed description with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention, and do not break away from the essence and the scope of technical scheme of the present invention.
