摘　　要：在现有的农业生态系统中,引进某些新物种,往往可以使整个系统的功能发生变化。如果新物种引进得当,则可产生良好的效果,系统功能得以改善,效益提高;反之,则会造成人力、物力、财力的损失,削弱系统的功能,甚至可能遗患无穷。因此。The purpose,principle and method of introducing novel species to an agroecosystem are discu-ssed from the viewpoints of agroecology and systematics.The main purposes of introducingnovel species should be:expanding production,increasing profits,eliminating or controllingpollution and increasing the stability of system.The principles which should be observedare:principles of system organization,principles of ecological niche and principles of dy-namic development.Finally,methods for feasibility study in introducing novel species andsteps for noevl species introduction are commented.
