摘要: 以江苏南部农村工业发达地区的吴江市为研究范例,采用系统动力学模型模拟分析方法,分析农村工业发展对农业生态系统的影响。结果表明,农村工业的发展对农业生态系统有正负两方面的影响,正影响表现为提高农民收入、增加农业投入、转移农村劳力等;负影响表现为导致耕地减少和环境污染等。农村工业实力增强后,若其产值利润以一定的比例用于发展农业和治理环境,将能减弱或避免农村工业给农业生态系统带来的负影响,达到农村工业与农业的协调发展。

关键词: 农村工业, 农业生态系统, 系统动力学模型

Abstract: A system dynamic model was used to analyze the impact of development in rural industry on agroecosystems in Wujiang city, a rural industrialized region of southern Jiangsu Province. The results show that there are both positive and negative impacts of rural industrialization on agroecosystem. The positive impacts display an increase of farmer's income and agricultural input, and a transference of promoting rural labors, while the negative impacts show a decrease of cultivated land and a result of environmental pollution. The negative impacts could be weakened or avoided, and the rural industry could be coordinately developed with agriculture, if a proper proportion of profit gained from rural industry would be used for agricultural development and environmental control after the actual strength of the rural industry was increased.

Key words: Rural industry, Agroecosystem, System dynamic model
