养殖水面

盐田、水库水面、养殖水面，面积总体呈增加趋势。

The areas of breed surface , salt pan and reservoir increase .

除养殖水面和农田景观有所增长外；水域、海洋、滩涂、林地景观都呈现了下降的趋势。

Except fish pond and farmland landscape increased , water area , marine , tidal flat and forest landscapes all decreased .

杭州湾湿地资源丰富，河流、湖泊、水库、养殖水面、滩涂等湿地类型多样，分布广泛。

Hangzhou Bay wetland is rich in resources with various kinds of rivers , lakes , reservoirs and water surfaces for Breeding , beaches widely distributed .

研究区内人工湿地主要包括水库及养殖水面，人工湿地的破碎化剧烈升高，主要由于余杭区重视水产养殖的发展，积极发展渔业，人工养殖水面相应增加且彼此之间缺少连通性。

Artificial wetland mainly includes reservoirs and aquaculture , and artificial wetland fragmentation dramatically rise , mainly due to the development of attention for aquaculture in yuhang district , and water aquaculture increase but lack of connectedness .

养殖水域水面冷却对流过程的数值实验

A numerical experiment of convection course driven by surface cooling in aquatics waters

以简单矩形水域为例，利用数值实验方法，定量探讨了具有自由水面的养殖水域由于水面冷却而引起的对流演变的过程。

Based on a numerical experiment carried out with a simple rectangular water area as an example , the paper discussed the developing progress of convection driven by surface cooling in aquatics waters with free surface quantitatively .

分析了造成水面锐减的原因，首先是水土流失造成的湖库淤积，其次是围海造田、围海养殖出现的蚕食水面；

The first reason of the reduction of water surface is sedimentation caused by soil erosion ;
