Key Technologies and Models for Ecological Governance and Ecological Derivative Industry Collaborative Development in Pisha Sandstone Area
In order to promote the high-quality development of soil and water conservation and ecological governance,it is an important issue to explore the key technologies and ways of the collaborative development of ecological governance and ecological derivative industries.There-fore,based on the theories and methods of ecological economics and ecological industry technology,the key technologies and models of the collaborative development of ecological governance and ecological derivative industries in Pisha sandstone area were explored,and the appli-cation demonstration was carried out.a)The principle of the coordinated development of ecological governance and ecological derivative in-dustries was that behaviors were driven by each other and effects were compensated each other,and the principle that should be followed was"double law adaptation,suitable place and livelihood,and tripartite willingness".b)The research and development of key technologies and measures for the coordinated development of ecological governance and eco-derived economy in small watershed of Pisha sandstone covered soil,covered sand and exposed areas.c)The key technologies of physical-chemical-biological integrated improvement of PSA sandstone soil,PSA sandstone combined with aeolian sand soil+biological improvement,optimal stubble leveling of shrub grass,utilization of coal gangue modified resources,corrosion resistance,seepage control,planting stabilization of high steep slope,and planting model of cash crops were proposed.d)Through the practice of"soil improvement and sand fixation+"in the sand-covered area,such as economic forest fruit planting,saxylon interplanting licorice and other ecological governance models,the"multi-investment,multi-participation and common benefit"mech-anism and operation mode of"government support,scientific and technological support,enterprise industrialization+public welfare invest-ment,and market participation of farmers and herdsmen"were explored.Through the pilot industrialization of grain and grass processing,soil improvement,and cash crop planting,as well as the demonstration practice of ecological restoration in mining backfill area,ecological gov-ernance in small watershed and collaborative development of ecological derivative industries,it shows that the development of ecological de-rivative industries in the management of fragile ecological areas has broad prospects.
