“973”项目“农林危险生物入侵机理与控制基础研究”简介

An introduction to "973" program "invasion biology and control strategy of alien species in agriculture and forest"

2002年12月,国家重点基础研究发展计划("973"项目)"农林危险生物入侵机理与控制基础研究"经科技部批准正式立项,2003年启动。文章主要介绍该项目的立项背景、主要研究内容、研究方案和技术路线、总体研究目标及研究进展。

This project selects representative invaded and potential invasive alien species （IAS） to investigate the three key issues in invasion biology, including genetic diversification in early stage of invasion, ecological adaptation in the stage of spreading, and risk assessment for prediction of potential IAS. The key scientific issues will be explored at the molecular, individual, population, community and ecosystem levels using molecular biology, molecular ecology, ecology, ecological genetics, biochemistry and other theories or methods. The main contests of the program include： genetic differentiation and rapid evolution, molecular-ecological and chemical-ecological mechanisms in the processes of population growth and expansion, impacts on the structure and function of ecosystems, resistance mechanisms of ecosystems to IAS, establishment and spreading possibility analysis of several potential dangerous IAS, molecular basis and techniques for rapid monitoring and diagnosis of IAS. The project will investigate and develop prediction systems and risk management paradigms for invasive species, and provide the scientific and technological support for the control of invaded species.
