Based on the characteristic weather/climate in normal years and natural resources for farming over the agricultural development/demonstration area of Jianmin, Jinhu country, northern Jiangsu, a group of models are developed for planning optimized cultivation for a range of weather/climate patterns on a yearly basis with the aid of science of system engineering. Evidence suggests that under the direction of the models, can be guaranteed a steady harvest of food crops in excess of 15,000 tons each year and oil crop yield and net economic benefit could be made to reach maximum as well.
