西北黄土高原夏闲地开发可行性决策咨询系统

The Feasibility of Developing Summer Fallow Land on the Loess Plateau in Northwest China

针对西北黄土高原地域辽阔，自然和社会生产条件差异大的特点，为解决实行多熟种植开发夏闲地决策难度大的问题，研制了西北黄土高原夏闲地开发可行性决策咨询系统。该系统能够按照给定的条件进行自动推理和判断，提出夏闲地开发可行性决策方案。根据某一生产单位或地区的具体生产条件，通过人机对话的形式，可迅速地逐步分析热量、水分和社会经济条件的可行性，并给出可能的多熟作物组合形式和复种指数，为夏闲地开发提供初步方案。

Based in the characteristics of vast land areas and great differences innature and social production conditions on the Loess Plateau in Northwest China,thefeasible decision-making inquiry systen of Developing summer fallow land on the Loessplateau has been developed in order to solve the difficult problem of decision-makingfor implementing multiple cropping system and developing summer fallow land.Thissystem can carry out auto-inference and judgement and work out the feasible decision-making scheme for developing summer fallow land in accordance with the given condi-tions. Based on one production unit or the concrete production conditions in one area,the system can analyse the possibility of heat,water and social economic conditionsthrough the dialegues between man and machine rapidly and gradually and work out thepossible multiple cropping combination patterns and multiple index so as to provide apreliminary scheme for developing summer fallow land.
