In this paper, a fire prevention concept with refined forecast and early warning of forest fire danger weather ratings in townships as the starting point, satellite real-time observation of fire spots, monitoring of the Internet of Things and other high-tech products as an implementation means, and strengthening forest fire prevention equipment and personnel in townships as a guarantee was established. The command system for rapid emergency response by cities, counties and townships should be improved. During the forest fire prevention period, fire sources should be strictly controlled, and the basic principles of forest fire fighting in townships should be implemented into the actual fire prevention and fire fighting work to eliminate forest fires in time at the initial stage and before the disaster.展开更多

But due to the uneven economic development, the agricultural development level of different land forms differs greatly and there is still a large gap between the incomes of urban and rural residents. In this paper, through an in-depth analysis of the farmers' income, agricultural industrial structure and urban-rural income gap in different mountainous areas of Zhejiang Province, some advices were proposed to increase the farmers' incomes.展开更多

During the period of phytoplankton bloom, phosphate content may be exhausted and, at thesame time, oxygen content in sea water increases in the euphotic layer. With the decomposition of or-ganic matter, phosphate content increases and oxygen content decreases in the deeper layer. In addi-tion, the upwelling carries the "new" nutrients to the euphotic layer, which provides advantageous展开更多

On the basis and through a systematic comparison of the products of magmatism in thearea, it is considered that there exists a compsite volcanic structural belt composed of linear and circular struc-tures and it has been demonstrated that there exist volcanic intrusive complexes--'trinity' composed of vol-canic, subvolcanic and plutonic rocks. It is suggested that the volcanic intrusive complexes in the area belong tothe typical syntexis series and that its materials were derived from a mixed source of crust and mantle.展开更多
Previous studies have shown that there are some ca.770–750 Ma mafic dykes at the western segment of the Neoproterozoic Jiangnan orogen(JO),and they represent post-orogenic magmatism due to orogenic collapse(Wang
