摘要
温饱问题基本解决后 ,长江中游洪区的三元种植业结构已不适应日益多元化、优质化的市场需求 ,早稻过剩、饲料粮短缺 ,再加上连年洪灾 ,农民增收减缓。本文立足当地自然资源和社会经济条件 ,结合当前国内外经济发展形势 ,以轮作方式为决策变量 ,运用线性规划法 ,分别预测了该地区 2 0 0 0年、2 0 0 5年和 2 0 1 0年的种植业结构变动情况 。
The grain_cash crop cropping sysytem has not been suited the increasing varied and high quality demand since sufficient food supplying in the flood area of middle reaches of Yangtze River Therefore, farmer's income increasing ratio has been slow down cause the low quality early rice and cotton surplus, forage grain shortage, and the year's exceptionally serious flood. This study focused on this situation, based on local agricultural natural resource, social economic factors, combined domestic and international market circumstances, used crop rotation as variables and linear programming method, forecated three alternate optimum cropping systems for 2000,2005 and 2010,and provided several policy suggestions.
