摘要
梯田生态系统是广东连南瑶排梯田国家湿地公园中的主要生态系统,但是,目前该湿地公园的梯田弃耕现象严重,当地农民接受生态补偿的意愿较强烈。采用机会成本法、市场价值法、当量因子法和影子工程法,估算该湿地公园梯田生态系统服务总价值;采用条件价值法,对与梯田利益相关的农民的“复耕还湿”态度和接受生态补偿意愿进行调查,以确定生态补偿标准下限。研究结果表明,2019年,广东连南瑶排梯田国家湿地公园的梯田生态系统服务价值为492.19×10^(4)元,正服务价值为505.63×10^(4)元,负服务价值为13.44×10^(4)元,单位面积价值量为38 042.20元/hm^(2);其中,水文调节服务价值最高,为261.92×10^(4)元,占正服务价值的51.80%,其次为食物生产服务价值,为159.20×10^(4)元,二者之和占正服务价值的83.29%,二者对梯田生态系统正服务价值起着重要作用;100户农民接受生态补偿意愿的调查结果显示,在梯田实施生态种植的前提下,79.31%的农户愿意接受生态补偿,并且愿意继续耕种梯田,接受生态补偿金额的范围为5173.80~6478.20元/(hm^(2)·a),20.69%的农户不愿意继续耕种梯田,但是接受政府租赁梯田,接受租金的金额范围为7416.60~8916.60元/(hm^(2)·a)。
The terraced rice field ecosystem in Yao Row Terrace in Liannan,Guangdong is a specia ecosystem,but the rice fields in the park are seriously abandoned and local farmers are more willing to accep ecological compensation.The opportunity cost method,market value method,equivalent factor method and shadow engineering method were used to estimate the total value of ecosystem services in the wetland park the conditional value method was used to investigate the attitude of farmers related to the interests of the terraced rice fields and their willingness to accept ecological compensation,so as to determine the lower limi of ecological compensation standard.The results showed that in 2019,the value of ecosystem services of terraced rice fields in Guangdong Liannan Yaopai National Wetland Park was 492.19×10^(4)yuan,with a positive value of 505.63×10^(4)yuan and a negative value of 13.44×10^(4)yuan,and the amount of value per uni area was about 38 042.20 yuan/hm^(2).Among them,the greatest among the indexes was hydrological regulation services,totaling 261.92×10^(4)yuan,accounting for 51.80%of the positive value,followed by the value of food production 159.20×10^(4)yuan,the two together accounted for 83.29%of the positive value,and played an important role in the positive value of the ecosystem.The results of the survey on 100 peasant household willingness to accept ecological compensation showed that 79.31%of households investigated accepted compensation and continue to cultivate under the premise of ecological cultivation in terraced fields,and the amount of ecological compensation they accept ranges from 5173.80 to 6478.20 yuan/(hm^(2)·a),while 20.69%of households investigated were not willing to continue to cultivate but accepted the government lease of farmland,and the amount of rent they accept ranges from 7416.60 to 8916.60 yuan/(hm^(2)·a).
