Abstract
The restoration of the ecological environment in rocky desertification areas and economic development go hand in hand. With the support of the national policies from the “Ninth Five-Year Plan” to the “Thirteenth Five-Year Plan”, the related ecological industries and products derived from the control of rocky desertification in karst areas continue to emerge. It not only restrains and repairs the development of rocky desertification but also produces a higher regional economic value than the replaced industry, which has practical significance for targeted poverty alleviation and rural revitalization in rocky desertification areas. The thesis classifies and summarizes the development status of ecological products from the perspectives of the basic theory of ecological products, industrial model construction, industrial demonstration, quality monitoring and evaluation, product sales space, product value realization and improvement research and proposes some scientific problems to be solved. The dual attributes of ecology and economy of ecological products are integrated, and a sustainable industrial model and industrial value-added enlightenment for consolidating the achievements of rocky desertification control is proposed.
Highlights
South China Karst is an area with the largest exposure area of the three karst concentration areas in the world
This paper summarizes the research on the ecological industry of karst rocky desertification control by scholars at home and abroad in the last 50 years, including the main achievements of this research on the scale, industrialization and commercialization of the ecological industry, and classifies and summarizes it according to the year, region, unit and content
In terms of ecological value accounting, the commonly used theoretical methods are mainly divided into three categories: actual market method, alternative market method and virtual market method and related extension methods, which have been applied in practice, mainly through the equivalent factor method (EFM) and the functional price method (FPM) [56]
Summary
South China Karst is an area with the largest exposure area of the three karst concentration areas in the world. To seek the healthy development of ecology and economy in karst areas, many scientific researchers have explored ecological industries suitable for local rocky desertification control and economic development in combination with the fragile karst environment and local reality and formed an ecological industry technology and promotion model for comprehensive rocky. The ecological industry model considers socio-economic development and environmental restoration [9,10] It is favored by farmers and scientific and technological personnel and is widely promoted, forming derivative ecological industries and products under the governance of karst rocky desertification. The ecological derivative industry of karst rocky desertification control has extended from basic theoretical research to model construction, industrial demonstration, monitoring and evaluation, sales space, value realization and so on. It is expected that this review will provide a scientific basis for future rocky desertification control work, promote the smooth promotion of rocky desertification control projects and realize the unity of ecological and economic benefits of karst fragile ecological environment
