Ganzhou, a typical red soil hilly area in Jiangxi province, is a pilot area for high-quality development of soil and water conservation in China. Through a series of following innovative initiatives, soil erosion in Ganzhou has been effectively prevented and controlled.
To strengthen the construction of smart water conservancy, Ganzhou has improved the ability to supervise soil and water conservation and to prevent human induced soil erosion. With the support of big data, cloud computing and other related information technologies, Ganzhou has established a "sharing and co-governance" regulatory mechanism, explored the "quasi real-time + refinement" regulatory mode, created an information sharing platform for soil and water conservation of production and construction projects, implemented the "joint review, joint approval and commitment" system for hilly economic fruit forest development. For soil and water conservation of production and construction projects, Ganzhou has promoted the commitment system of soil and water conservation plans, and carried out information based on supervision of soil and water conservation in both regional and key production and construction projects in all jurisdictions, achieving full coverage, normalization and standardization of soil and water conservation supervision for production and construction projects.
By summarizing the construction experience of Shangyou County Yuancun (Fig. 1) and Ningdu County Goudaozui (Fig. 2) National Ecological Clean Small Watershed, Ganzhou has explored a new pattern for the construction of ecological clean small watersheds: governing a clean small watershed, revitalizing a village, creating a demonstration project, cultivating a green industry, and making people rich. Through the construction of ecologically clean small watersheds, the soil and water loss control and regional economic development have been achieved in a coordinated way to better benefit the local people.
Ganzhou is a concentrated distribution area of collapses. Bank loans and government bonds have been comprehensively used to raise funds for collapse control, and the open competition mechanism to select the best candidates has been established, and also the substituting awards for subsidies have been used to efficiently allocate collapse control bunds. In addition to ecological protection type and engineering restoration type collapse control mode, the creative collapse control mode with efficient development has also been put forward for concentrated continuous collapses control (Fig. 3). By demonstrating and promoting from point to area, the collapse control has become a kind of hot investment projects, which attracted the participation of social capital, realizing the diversification of control fund sources and investors. The control measures are gradually becoming systematization, and the control effects are realizing integration.
