In consideration of the relative principles such as systematic engineering, ecological agriculture, a-gricultural meteorology,
crop cultivation and technological economy, the ecological system property of farmland in waterlogged land in Jianghan plain was analyzed, and the current
plantation system and newly developed
high effective agricultural model were assessed in the present study. Four kinds of suitable and high effective plantation and/or aquaculture models are proposed: 1) steaby grain production and the development of rape production for the increase of production value, 2)steady cotton production and flesible utilization also for the increase of production value, 3) grain and economic crop or forage crop for poultry and livestock, 4) combination of land cultivation and fertilization. These four models have following optimum functions, such as variety of products, structures, large-scale flood mitigation. However, it must be pointed out that the high effective agricultural model itself needs the rotation of paddy and upland crops, and the rotation between high effective model and traditional cultivation system is essential in order to achieve sustainable development. In addition, the four models have a broad prospect for in the applicationin in the southern region of the waterlogged land in Jianhan plain.
