摘要
以Agent强化学习概念模型理论原理为基础,从农户Agent的感知A(Agent对环境的感知器)过程、学习过程L(Agent的学习器)、决策过程P(Agent的决策选择器)和在环境上的落实过程E(Agent决策实施的环境)4个模块构建农户后顾生计来源Agent决策模型.结果表明:农户后顾生计来源Agent决策模型能准确定量表达政策、市场、农户自身及与其他农户相互作用等因素对农户后顾生计来源决策的影响并对其予以识别;种植大田作物、经济作物(柑、桔)、养殖家禽水产(猪、鸭、鱼)、个体经营(小商店)和外出务工为研究区农户主要后顾生计来源;农户后顾生计来源因农户内外条件和响应政策能力的差异而呈现出不同,2%的农户放弃农耕,其后顾生计来源为非农就业,23%的农户以大规模种植经济作物和养殖家禽水产为主导,其后顾生计来源为农业专业化经营,75%农户以个体经营和外出务工为主,其后顾生计来源为兼业化经营.
The source of the forward-security of farmers＇ livelihood is a decision making behavior caused by farmers＇ reaction to policy, game of the external environment and their own conditions. The result isrelat ed not only to their consumption of production life and construction, but also to the formulation of policy of supporting agriculture and benefiting farmers and the improvement of people＇s livelihood. In this paper, based on the theory of reinforcement learning, an Agent decision making model is built for the source of forward security of farmers＇ livelihood, including four modules, i. e. an Agent environment sensor, an A genl learner, an Agent decision selector and an Agent decision-making implementer in environment. The following results are obtained： first, the Agent decision-making model of the source of the forward securi ty of farmers＇ livelihood can accurately and quantitatively express the effects of policy, market, farmers and their interaction with other farmers on the decision-making of the source of the forward-security of farmers＇ livelihood and recognize them. Secondly, the sources of the forward-security of farmers＇ liveli hood in the study area mainly include cultivation of field crops and cash crops （oranges and tangerines）, breeding poultry and aquaculture （swine, duck and fish）, doing selLemployed business and working away from their hometown as migrant workers. Thirdly, the sources of the forward-security of farmers＇ liveli hood vary with farmers＇ internal and external conditions and their response to policy. In the study area, 2% of the farmers give up farming, whose source of the forward-security is non farm employment, 23% work on large scale cultivation of cash crops and breeding poultry and aquaculture, whose source of the forward security is professional management of agriculture, and 25% do self employed business or work a way from their hometown as migrant workers, whose source of the forward security is part time opera lion.
