摘要
微观层面模型对于区分不同的人口群体以更好地明确环境退化的责任主体及其原因具有重要价值,对不同的土地利用方式进行经济区分是联接家庭人口特征与土地覆盖结果的重要手段。基于扩展的恰亚诺夫理论框架,文章利用2007—2008年两次调查所获293个农户样本数据,采用OLS和logit多变量模型实证分析毛乌素沙地家庭人口和其他因素对土地利用的影响。研究结果表明:(1)家庭人口因素对毛乌素沙地农户的土地利用产生重要影响;(2)毛乌素沙地主要土地利用的环境影响也遵循家庭生命周期的过程;(3)毛乌素沙地农户在减少有助于土壤修复利用活动的同时面临上升的退化风险。
Micro level models are of great value for distinguishing different population groups in order to better clear the responsible party for environmental degradation and the reasons. The economic distinction among different land use patterns is an important means of linking domestic demographic characteristics to land cover outcomes. Based on the extended Chayanovian theoretical framework, this paper drew on multivariate models to analyze effects of household demography and other factors on land use outcomes by using data of 293 sample households from two surveys during 2007-2008. The empirical results show that： （1） household demographic factors exert significant effects on land use in Mu Us desert; （2） the environmental impacts of predominant land uses also follow the course of household life cycle; （3） households in Mu Us desert reduce activities contributing to soil remediation while facing a rising degradation risks.
