摘要
对畜菜互补系统和由畜、菜、沼气池共同组成的畜菜互补能源自给生态系统的原理、产生和发展进行了分析,介绍了能源自给生态系统的几种典型结构,并对其性能进行了分析。指出了该系统存在的一些有待解决的问题,如畜、菜和沼气池之间的配比关系尚无理论及实验依据,互补有效期短且效果差等。
The principle and development of plant and animal complementary sys- tem,plant and animal and methane pond complementary ecosystem with energy self-supply are analysed.Some typical structure forms of the ecosystem are intro- duced and their performance are discussed.The existing problems which must be solved are presented,such as the ratio selection of animal heads,plant area and methane pond volume,their effective periods and effectiveness.
