摘要
以米脂县孟岔村为研究对象,通过设计农户问卷,将研究区农户划分为种粮农户、打工农户、种果农户、种粮兼顾打工农户等四大类,并利用GIS、GPS技术将土地利用的空间信息和农户微观主体的社会经济行为与特征联系起来。随后使用完全信息静态博弈,建立了不同类型农户的两两博弈关系模型,通过模型分析得出:(1)农户以自身利益最大化为决策目标,并考虑了其他农户的决策行为对其产生的影响,孟岔村最终形成了"少数农户承包旱地经营果园,部分农户承包水浇地,部分农户完全脱离土地外出打工,大部分农户农忙时种粮和农闲时打工"的土地利用和家庭经营模式;(2)上述土地利用模式使研究区域土壤侵蚀量有了明显的降低并有效地增加了农户的收入。
A pattern of static games of complete information was set up to analyze land use change of Mengcha Village in Mizhi County of Shaanxi Province based on farm household questionnaires from geography and economics perspectives. Through ways of GIS and GPS, land use spatial information was connected with farm households＇ social and economical behaviors characteristics. With maximizing benefits as the goal, new land use and household business patterns formed in the village, in which the minority of the households contracted rain-fed land for orchard, some contracted irrigable land, some gave up land completely and went out for hired working, while the majority worked for farming in busy seasons and went out for hired working in slack seasons. The new land use patterns achieved double-win effects both economically and ecologically.
