江西省上饶县农户水土保持投资行为机理与实证模型

以农户调查数据为基础，通过对农户水土保持行为机理分析，结合研究区域实际，确定区域经济发展水平、农户兼业经济行为、农业经营规模、劳动力状况等4大类因素为影响农户进行水土保持投入的主要因素，并进一步细化成9项具体指标。通过SPSS软件对各项指标与水土保持投入行为进行相关性分析，建立多元线性回归模型，发现农户兼业经济行为、农业经营规模是影响农户进行水土保持投入的主要限制因子。由于兼业和规模经营对农业收入的依赖程度较低，且防范农业风险的能力较强，农户往往不愿意进行水土保持投资。家庭收入主要来源于农业，以及农业人口比重较高的农户，往往会在水土保持上投入较多的时间和资金。针对农业劳动力不足、农业经营规模小等现状提出如何激励农户水土保持投资行为，以进一步促进水土流失治理的相关建议。

FARM HOUSEHOLDS' BEHAVIOR IN RELATION TO WATER AND SOIL CONSERVATION INVESTMENT (WSCI) IN SHANGRAO COUNTY OF JIANGXI PROVINCE

Based on the farm household′s questionnaire in Shangrao County of Jiangxi Province, the paper analyzed the mechanism of farm households′ behavior of WSCI. Factors, influencing mostly farm household's behavior of WSCI are: regional economic development, part farm behavior of farm households, agricultural land area and quantities of family agricultural labor. In order to analyze the relativity between farm household′s behavior of WSCI and these parameters, a linear regression model was established by the software SPSS. Farm household′s behavior of WSCI was mostly influenced by part farm behavior, income structure and agricultural land area of farm households. Part farm households, who had more income from non agriculture, invested less in water and soil conservation. And farm households with more agricultural land area also paid less attention in investing water and soil conservation. At last, some pieces of advice were given to prompt farm household′s behavior on WSCI.
