摘要

草地被称为“地球的皮肤”,是陆地上最大的生态保护屏障,其提供了大量生态产品价值。本研究以高寒地区青海省海西蒙古族藏族自治州天峻县为例,以其草地资源丰富的资源禀赋特征为出发点,构建差异化的生态产品价值核算体系,并从物质供给、调节服务和文化服务3个方面,运用水量平衡法、土壤流失方程等方法核算天峻县草地生态产品价值,提出草地生态产品价值转化路径。结果表明,天峻县草地生态产品价值实现以生态保护和生态补偿为主。天峻县草地生态系统生态产品总价值约为152.06亿元,其中物质供给价值约为3.60亿元,约占总价值的2.37%;调节服务价值约为144.22亿元,约占总价值的94.84%;调节服务价值中,局部气候调节价值>水源涵养价值>固碳释氧价值>土壤保持价值;文化服务价值约为4.24亿元,约占总价值的2.79%;草地生态产品调节服务的价值最大,符合青海省“三个最大”的省情定位和高寒地区资源禀赋特征。探索草地生态产品价值,有助于政府制定生态补偿政策,促进资源合理利用和可持续发展,为草地资源的保护和高质量发展提供参考。

Abstract

Grassland, known as the “skin of the earth”, is the largest ecological protection barrier on land, which provides a lot of ecological product value. This study took Tianjun County, Haixi Mongolian and Tibetan Autonomous Prefecture, in the alpine region of Qinghai Province as an example, constructed a differentiated ecological product value accounting system based on the characteristics of rich grassland resource endowment. From three aspects of material supply, regulation service and cultural service, this paper used the water balance method and soil loss equation to calculate the value of grassland ecological products in Tianjun County, and proposed the value transformation path of grassland ecological products. The results showed that the realization of the grassland ecological products value in Tianjun County mainly relied on ecological protection and ecological compensation. The total value of ecological products of grassland ecosystem in Tianjun County was around 15.206 billion yuan, of which the value of material supply was around 360 million yuan, accounting for around 2.37% of the total value, the value of regulation services was around 14.422 billion yuan, accounting for around 94.84% of the total value. Among the regulation service value, the value of local climate regulation> water conservation> carbon sequestration and oxygen release> soil conservation value. The value of cultural services was around 424 million yuan, accounting for around 2.79% of the total value. The value of grassland ecological product regulation service was the largest, which was in line with the provincial positioning of “three largest” and the characteristics of resource endowment in alpine region of Qinghai Province. By exploring the value accounting of grassland ecological products, this paper is helpful for the government to formulate ecological compensation policies, promote the rational utilization and sustainable development of resources, and provide references for the protection and high-quality development of grassland resources.
