红河哈尼梯田遗产区生态系统服务价值外溢研究

传统农业生态系统服务的价值外溢效应评估有助于提高对该农业生态系统服务价值的正确认知,为合理规划区域社会经济产业结构以及生态安全布局提供科学依据。以云南省红河哈尼梯田遗产区为例,采用基于单位面积当量因子方法估算哈尼梯田遗产区农业生态系统服务价值,并采用市场价值法和旅行费用区间法估算梯田景观的生产服务价值和休闲旅游服务价值,厘清哈尼梯田遗产区农业生态系统服务价值特征,探究传统农业生产景观的服务价值外溢情况。结果表明：(1)1995—2018年,研究区土地利用总体变化不显著,而建设用地面积相对增加较多,变化率为59.3%;(2)哈尼梯田遗产区农业生态系统服务价值总量减少了811万元,变化率为0.6%;农业生态系统服务结构保持稳定,一级服务类型中,调节服务价值量最大,二级服务类型中,气候调节服务价值量最大,食物和原材料生产价值贡献率仅为6%,水资源供给服务价值为负值;(3)2018年元阳哈尼梯田景观的粮食生产服务价值为0.8×10⁸元,休闲旅游服务功能价值为1.3×10⁸元。元阳哈尼梯田生态旅游促进区域可持续发展,梯田农业生产景观具有明显的价值外溢效...

Spillover of ecosystem service value in Honghe Hani Terrace Heritage Area

Evaluation on the spillover effect of traditional agroecosystem services is helpful to improve the correct cognition of agroecosystem services and can provide scientific basis for the rational planning of regional socio-economic industrial structure and ecological security layout. Taking the Hani Terrace Heritage Area in Yunnan Province as an example, we used the unit area equivalent factor method to evaluate agroecosystem services. Aiming to clarify characteristics and value spillover of agricultural ecosystem services in the study area, we selected the market value method and the travel cost interval method to estimate the production service value and leisure tourism service value of the terraced landscape. The results showed that:(1) From 1995 to 2018, the overall change in land use in the study area was not significant, while the area of construction land increased relatively much, with a change rate of 59.3%. (2) The total value of agro-ecosystem services in the Hani Terrace Heritage Area decreased by 8.1×10⁶ yuan, with a change rate of 0.6%; the agricultural ecosystem service structure remained stable. Among the first-level service types, the value of regulation service was the largest, while among the second-level service types, the value of climate regulation service was the largest. The contribution rate of food and raw material production value was only 6%, and the value of water resource supply service was negative. (3) In 2018, the grain production service value was 0.8×10⁸ yuan, and the value of leisure tourism service was 1.3×10⁸ yuan. The eco-tourism promotes the regional sustainable development, and the terraced agricultural production landscape has obvious value spillover effect.
