Evaluation of linkage efficiency between manufacturing industry and logistics industry considering the output of unexpected pollutants.

Applied a non-radical non-oriented Slack Based Measure (SBM) model of Data Envelopment Analysis (DEA) to measure the linkage efficiency between the two sectors from 2009 to 2016. The paper analyzes the current situation of manufacturing and logistics efficiency, presents a way to improve the linkage efficiency of manufacturing and logistics industry, and using Tobit regression to analyze the environmental factors that affect the linkage efficiency. The results show that: Totality, the two industries in the three northeast provinces show a steady development trend in the period from 2009 to 2016, but the development of the two industries in northeast China is still insufficient.

[Investigation of snails in Anhui Province in 2016].

Objective: To investigate the status of snails in Anhui Province in 2016, so as to provide the evidence for formulating the 13th Five-Year Plans for Schistosomiasis Control.

Methods: In 2016, a snail survey was conducted in Anhui Province according to the , covering all snail habitats or historical snail habitats and suspected environments of snail breeding, and the results of the survey were analyzed.

Results: In 2016, 22 848 environments were surveyed, and no schistosome-infected snails were found.

[Application of infrared camera technique in investigation of wild animals as infectious source of schistosomiasis].

Objective: To investigate the species and activities of wild animals infected with schistosome in hilly and mountain areas by using an infrared camera technique, so as to provide the evidence for the surveillance of schistosomiasis in these areas.

Methods: Six infrared cameras were selected and placed in 6 environments of the risk monitoring points of schistosomiasis in Shitai County in Anhui Province. The species and activities of the wild animals in the 6 environments were observed through the photographs and videos taken by the cameras.

[Dynamic change of population structure of ].

To understand the successive dynamic change of population structure of during a one-year period, so as to provide the evidence for snail control. A river beach and a ditch infested with snails were selected and longitudinally investigated in the midmonth during one year. The snail survey indices included the survival status, gender, number of whorls, length and width of shell, and gonad development status (measured by the color depth of gonad and the length ratio of gonad to liver), and the monthly snail eggs in the soil were collected and counted simultaneously.
