Furthermore, the major tasks of wetland agronomy include the basical research of the wetland agriculture,the key technique research of wetland agriculture,the transformation and application of the achievements in the studies of the wetland agriculture.
This article discusses the obstacle factors of sustainable development on Jianghan plains's wet land agriculture,the sustainabel development target of ecological stereo agriculture of wet land and also puts forward three relative measures

With a long history of agricultural exploitation and a high level of agricultural production,the Dongtinghu wetland is an important agricultural commodity base.
The results showed that the wetland landscape pattern structure will reach relatively steady state at the future period, that is, natural water area was 9.27%, man made water area 11.23, bottomland 0.67%, paddy field 51.93%, non wetland area 18.21%, and urban and rural area 8.69%.
The paper analyses the conditions for sustainable development of agricultural resources and the status of agricultural exploitation in this area,and puts forth some problems in the exploitation and some ideas for it. It is useful for the realization of sustainable development in this area.
In addition to the environmental concerns, we emphasize the need to consider the physical, socio-economic, and political contexts in which contemporary wetland agriculture would have to operate.
Based on the environmental and natural characteristics of low-lying damp land in three-river plain, the plane ecological structure of "dryland field-paddy field-grass- field-fish pond" was formulated. While adjusting the ecological st ructurc, the ratio of input to output tor manpower auxiliary energy and the equilibrium of the farmland nutrients was analyzed or estimated scpcratcly, and the means of further development and perfection was put forward Analyses show that the system structure tends to be ratio...
A series of ecological counter measures have been studied in “Sihu”area,Jiang-han-Dongting plain,the piace which is famous for“water bag”,in the latest decade in order todevelop wetland agricuIture. The mecbanism;of high-yielding,high-efficiency of the fourtypes and nine models in vvater logged farmland have also been studied.Out of several decadesof models,the.“grain-cash crops type”,“grain-fish type”,“grain-fodder crops type”and“total grain type”are the unity of high-yielding,high efficiency and ecologica...
The study of the environmental quality of water,air and soil systems of 3 pollution free vegetable production bases located in mountain,hill and plain areas,as carried out in Jinhua City Zhejiang Province,and the status of vegetable production was investigated.Results showed that the environmental quality of all the 3 areas are good for pollution free vegetable production.The vegetables grown in the mountain area afforded high yield and good quality on account of the climatic feature of wide diurnal te...
