摘要
基于碳汇视角,用实地测量和农户调研数据测算了县南沟流域种植业的净碳汇量及其价值,以此表征种植业可实现的生态价值。结果表明:2001—2014年,种植业的生态价值总体上呈稳步递增趋势,由2001年的35.34万元增至2014年的901.71万元;种植业价值的演变过程可分为三个阶段,第一阶段(2001—2004年),经济作物>粮食作物>苹果园;第二阶段(2005—2010年),经济作物>苹果园>粮食作物;第三阶段(2011年至今),苹果园>经济作物>粮食作物;苹果园、粮食作物、经济作物生态价值占生态经济总价值比例的均值分别为58.22%,31.19%,3.60%,突显了生态价值的重要作用,为此在农业生产中,应综合考虑生态价值和经济价值来优化种植结构,发展低碳农业。
Based on the perspective of carbon sink, we calculated the net carbon sink of planting industry and its value by field measurements and accumulated 14-year peasant household survey data in the Xiannangou watershed, and evaluated the achievable ecological value of the planting industry. We also analyzed the ecological benefits of planting industry referring to the planting economic value. The results showed that the ecological value of the planting industry present the steady increasing trend, which increased from RMB353,400 to 9.02 million during the period from 2001 to 2014. The evolution of ecological economic value can be divided into three phases： the first phase （2001--2004）, commercial crops 〉 grain crops〉apple orchards; the second phase （2005 2010）, commercial crops〉apple orchards〉grain crops, the third phase （2011 to present）. In the carbon sink market, the ecological value of planting industry accounts for 42.28% of the total ecological and economic value. Among them, ecological value of apple orchards, grain crops, cash crops account for 58. 22%, 31.19%, and 3.60%of the total ecological economic value, respectively. That is to say, the ecological value of apple orchards has exceeded its economic value. The ecological value plays the increasingly important role. Therefore, the ecological value and economic value should be taken into comprehensive consideration to optimize planting structure in agricultural production, in addition, to reinforce the concept of low carbon pro- duction and progress the low-carbon agriculture. The government should introduce relevant encouragement policies and avoid influencing the ecological value for randomly expanding the scale of facility agriculture.
