Abstract:

Proceeding from the relation of forest biological disaster and eco-system function, the history of forest diseases and pests control, the strategy of forest pest control and the need of the targets of forest management, the paper defined the concept of Forest Pest Ecological Control (FPEC), analyzed the characteristics, academic and technological base of FPEC. Natural cybernetics and self-organization theory are the academic bases and forest ecosystem management is technological one. The paper discussed the roles of FPEC, including ecosystem rule, coordination rule, ecological balance rule, niche rule, environmental protection rule, coevolving rule, forestry by-product security rule, ecosystem stability rule, ecosystem high functional rule (high productivity, economic benefit, ecological benefit and social effects) and sustainable control rule of forest ecosystem bio-disaster. And also evaluates the FPEC and its suitable conditions. The authors think that FPEC has unquestioningly many merits compared with Forest Integrated Pest Management and it is the main research direction of forest pest control in the future. The strategy is bound to have a broad prospect.
