-low-frequency sea level fluctuations in the Hangzhou Bay in winter and summer, 1973-1974 are analyzed in this paper. The established multi-spectrum response models effectively identify the different dynamical factors and their contributions to the low-frequency sea level fluctuations inside the bay. The results show that the Ekman transport due to longshore winds is the major mechanism to induce the sea level fluctuations, more important than the frictional effect of local winds. There also exists obviously the influental effect of the free fluctuations of the continental shelf. In addition ,a simple estimation suggests that the remarkable sea level fluctuation of 0. 4 d-1 in the bay is related to the resonance of the Huanghai Sea and the Bohai Sea (taken as a single bay).

作者： Huang Daji chen Zongyong and Su jilan(Second Ingtitute of Oceanography, State Oceanic Administration, Hangzhou 310012, China)(Ocean University of Qingdao, Qingdao 266003, China)

The barotropic processes of tides, tidal currents, wind-driven currents and the interaction of winds andtides in the Bobai Sea are investigated with a three-dimensional shelf sea model. The tides and tidal currents are wellsimulated. The main characteristics of tides and tidal currents, such as the types of tides and tidal currents, co-tidaland co-range charts, co-current charts, tidal ellipses, mean tidal currents and tidal residual currents are presented. Apair Of cyclonic and anticyclonic headland eddies in the northern Bohai Straits is discovered. The tidal currents have little vertical structure except close to the sea bottom. Driven by strong winds, the currents have a significant three-dimensional structure. In response to coastal geometry and bottom friction, the wind drift in the upper layers is in the direction of the wind or slightly to the right. In depth, considerable compensating currents maintain a circulation balance. The interaction of winds and tides is locally strong. The oscillating tidal currents play a role of dissipating energy. Thus the usual purely wind-driven currents in the area of weak residual tidal currents are often overestimated in theabsence of tides.

目前，我国畜牧业大致分为牧区、农区和城市郊区三大格局。牧区以牛、羊等草食家畜为主，城市郊区则以畜禽集约化生产为特征，而在人口密集的中国东南部和中部广大农区，千家万户利用副产品、余粮和剩余劳动力养鸡，是农区农民重要的经... 详细信息

目前，我国畜牧业大致分为牧区、农区和城市郊区三大格局。牧区以牛、羊等草食家畜为主，城市郊区则以畜禽集约化生产为特征，而在人口密集的中国东南部和中部广大农区，千家万户利用副产品、余粮和剩余劳动力养鸡，是农区农民重要的经济来源之一。如何在新农村建设过程中，结合农区的自然环境和经济条件，从关键技术的应用推广着手，解决农民养鸡经济效益低、疫病控制难、环境影响大等问题，对于农区农民的富裕和生存环境的改善具有十分重要的意义。
