Abstract:: 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 production 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.
