Abstract：Soil and water conservation plays an important part in building ecological civilization and an effective way of improving quality and stability of ecosystems.Enhancing and maximizing functions of ecological service and value of soil and water conservation is of great significance.On the basis of reasonably defining the scope of ecological products and considering the relevant technical specifications and characteristics of soil and water conservation,a method is proposed to calculate the value of ecological products of soil and water conservation.Taking eco-friendly small watershed of Shimenkeng sourced from the Huangpujiang River in Anji County of Zhejiang Province as an example,the method had been put into practice and application.The results show that after more than 10 years of comprehensive control of soil erosion,the value of ecological products in this small watershed was 103.575 million yuan in 2023,accounting for 16.6%of the total,with a value-added rate of 19.9%.The value of ecological products per unit area was 18,200 yuan/(hm2·a).Based on conditions of small watersheds and market demand survey,we developed a way of transferring operation right of eco-tourism which relies on a platform of ecological product trading and competitive bidding to realize value transformation of some products.This helps to practice the philosophy of"lucid waters and lush mountains are invaluable assets"and form a replicable and promotable model for mutual benefits of ecology and soil and water conservation.
