【摘要】：利用条件价值法(CVM)对京郊农田生态系统的非使用价值进行了初步研究。以北京市居民作为调查对象,采用随机抽样的方法,共发放问卷1500份,回收有效问卷1323份,对有效问卷进行统计分析。结果表明:北京市居民的支付意愿率为66.2%,非农业户口与农业户口的北京居民的支付意愿分别为62.3%和66.7%,人均支付意愿值(中位值)为100元/a。2014年京郊农田生态系统的非使用价值约为142 421.45万元,相当于2014年北京市地区生产总值0.067%,其中,存在价值为38 487.89万元,遗产价值为49 693.23万元,选择价值为54 240.32万元。经Spearman相关分析表明:学历、月收入以及户口性质是影响居民支付金额的主要因素。
