食物网研究进展

Progress in Food Web Researches

食物网是群落中各种生物有机体通过营养关系连接成的集合体。关于食物网的基本结构、HSS与MS观点的争论、食物链长度、与食物网大小相关的特性、食物网连接中的问题以及小瀑布模型等等,都是食物网生态学研究的主题。这些问题的深入研究将为认识食物网中种群调控机制,营养级之间的关系、各种食物链的存在及其能量转化机制、生物群落的行为机制以及自然保护设计等等作出贡献。同时,对于食物网理论的进一步完善与发展,生态学理论与应用都具有重要的意义。

A food web describes which kinds of organisms in a community eat which other kinds, if any.There are many recent researching subjects about food webs: food web structure in general, arguing about HSS and MS, food-chain lengths, food-web properties in relation to food-web size, connectance in food web, and cascade model etc.Futher exploration about these problems would eventually contribute to the theoretical and applied ecology
