Study On The Reason Of Desertification And Restoration Tactics Of Kangping County, Liaoning Province

Sustainable management is the goal of all people in the world, and ecosystem service is the matter of humankind survival and development. But many ecosystems are degraded because of different worse factors and their ecosystem services are at a lower level, which are influencing and restricting the sustainable development of society and economy. For these reasons, it has important significance both in theory and in practice to carry out the study on restoration and reconstruction for degraded ecosystems.Taking Kangping county as the research object, the reasons and mechanism of degradation, the channels and ways to deal with the situation were studied in detail with the basic theories of restoration ecology adopted. And overall strategy for the sustainable development of resources and environment was put forward too in this paper. Climate variation, characteristics and the relationship between the both and desertification were analyzed. Natural and human disturbances and their combination function were considered the main reasons for the degradation of ecological environment in this area. The fragility of ecosystem of local area is the potential power for degradation of ecosystem, and the warm-dry trend of local climate and all kinds of human excessive activities resulting from the overgrowth of population are the direct reasons for the degradation. Disturbance system of ecosystem of Kangping county was put forward and established for the first time. The overall comprehensive program and emphasis projects were raised according to the theories of ecology and systems engineering. Fundamentals of synthetic control for wind-sandy environment were expounded. Some key problems and their solutions in the process of wind-protecting and sand-controlling, improvement of degraded grassland, construction of artificial grassland and the development of animal husbandry were discussed in detail. The directions and models of vegetation restoration and synthetic control of degraded ecosystem in Kangping County were submitted according to fundamentals of restoration ecology.
