摘要
苹果园作为一种农林耦合特殊生态系统,不仅提供农产品,还具有维持自然环境条件与效应的生态服务功能。该研究选取黄土高原残塬沟壑区永寿县苹果果园为评价区,构建评价体系。采用市场价格法、价值替代法等评价方法,评估苹果园生产农副产品、负效应等9项生态服务价值。结果表明:永寿县苹果园生态系统在2019年生态系统综合服务价值为41495.66万元,其中正效益为45096.33万元,负效益为-3600.67万元。在选取的9项苹果果园生态系统服务指标中,生产的价值最大,为21793.71万元,远大于其他生态服务价值。生物多样性保护(8247.49万元)>保育土壤(8066.69万元)>负效益(-3600.67万元)>涵养水源(2779.32万元)>文化娱乐(1814.83万元)>固碳释氧(1440.45万元)>净化调节(708.22万元)>林木养分固持(245.62万元)。黄土高原残塬沟壑区为中国水土流失重点治理区,苹果园为该地区林木重要组成部分,对其服务价值的研究,可以为该地区推动经济林建设、发展和可持续利用提供数据支持。
Apple orchard forest,as a special ecosystem combining agriculture and forestry,not only provides agricultural products,but also has the ecological service function of maintaining natural environment conditions and effects.This paper chose the apple orchard in Yongshou County in the gully region of the remaining plateau of Loess Plateau as the evaluation area and constructed the evaluation system.Evaluation methods like market price method,value substitution method and others were used to evaluate the production of agricultural and sideline products and negative effects of the apple orchard.The results showed that the comprehensive service value of apple orchard ecosystem in the County was 414.9566 million yuan in 2019,of which the positive benefit was 450.9633 million yuan,and the negative benefit was-36.0067 million yuan.Among the 9 selected ecosystem service indexes of apple orchard,the value of production is the most,which is 217.9371 million yuan,which is far more than other ecological service values,with the rank as biodiversity protection(82.4749 million yuan)>conservation of soil(80.6669 million yuan)>negative benefit(-36.0067 million yuan)>water conservation(27.7932 million yuan)>entertainment(18.1483 million yuan)>carbon sequestration and oxygen release(14.4045 million yuan)>purification and regulation(7.0822 million yuan)>tree nutrient retention(2.4562 million yuan).The gully regions of the remaining plateau are the key control regions of soil and water loss in China,and apple orchard is an important part of the forest in this area.The research on its service value can provide data support for promoting the construction,development and sustainable utilization of economic forest in these regions.
