Moreover,the microbial fertilizer standard system with Chinese characteristics has been firstly established by China in the world. Development of bio-fertilizer standard,especially the amplification and modification of bio-fertilizer product standard and the construction of bio-fertilizer standard system,etc. were summarized in this paper. Meanwhile,relative suggestions of existing problems were put forward.展开更多

Then its early warning-system frame was preliminarily constructed,which includes ecological security dynamic monitoring,ecological security appraisal,ecological security forecast and ecological security decision-making management. The synthetic evaluation indicator system of the ecological security quality were initially established,which includes ecological environment pollution,land use and land cover change,geological hazard and epidemic outbreaks. At the same time,29 evaluating indicators were selected,divides into the basic factors,response factors and inducing factors,which need to be Real-time monitored.展开更多
