Analysis on Human Comfort of Tourism Climate in Binzhou City

According to meteorological data at Binzhou Meteorological Station during 1981 -2010, basic climate characteristics of meteorological factors （such as temperature, relative humidity and wind velocity, etc. ） related to human comfort are analyzed, and temporal-spatial distribution characteristics of human comfort in Binzhou City are studied. Then, human comfort of tourism in Binzhou City is evaluated. The impacts of each meteorological factor on comfort in different seasons and change tendency of comfort are discussed, and the optimal tourism time in Binzhou City is analyzed.

A Study on Water Quality Monitoring in Urban Watercourse of Xinli River in Binzhou City

This paper aims to explore the pH,COD,ammonia nitrogen,total nitrogen,total phosphorus and other indices regarding Xinli River water in Binzhou City.The results show that the pH of the water quality index is between 7.3 and 7.8,slightly alkaline;the COD content of Xinli River is about 140-163 mg/L,and the COD pollution is serious in some water sections;the ammonia nitrogen content of Xinli River is 0.2-2.17 mg/L,the total nitrogen content is about 0.799-1.3 mg/L,the total phosphorus content is about 0.54-0.92 mg/L,suggesting that the water eutrophication is very serious.Due to the large amount of domestic sewage discharged into Xinli River without treatment,slow circulation of river water and other factors,the eutrophication is serious in the urban watercourse.

Preliminary Analysis on Observation Data of Acid Rain in Binzhou City of China

A total of 142 acid rain samples collected between 2006 and 2008 by Weather Bureau of Binzhou City were preliminarily analyzed to obtain acid rain profile and spatio-temporal distribution of pollutants in urban districts and suburbs of Binzhou City.The results showed that Binzhou City basically belonged to non-acid rain region with annual acid rain frequency of 4%-6%;pH value was greatly affected by acid pollutant concentration,wind velocity and dominant wind direction;conductivity correlated with impurity content in atmospheric precipitation.

Spatio-Temporal Distribution of Agricultural Non-Point Source Pollution in Binzhou City Based on Large Computer Data

Based on the relevant statistics on the agricultural non-point source pollution in Binzhou City,we studied the spatio-temporal variation in agricultural non-point source nitrogen pollution and phosphorus pollution in Binzhou City during 2008-2015. The results showed that the agricultural non-point source nitrogen pollution and phosphorus pollution in Binzhou City changed from 114400 t and 28800 t in 2008 to110600 t and 24400 t in 2015,respectively; for the non-point source nitrogen pollution sources,the proportion of chemical fertilizer,manure and domestic sewage changed from 80. 41%,10. 47% and 9. 13% in 2008 to 82. 94%,4. 77% and 12. 29% in 2015,respectively; for the non-point source phosphorus pollution sources,the proportion of chemical fertilizer,manure and domestic sewage changed from 89. 29%,8. 32% and 2. 39% in 2008 to 91. 6%,4. 78% and 3. 62% in 2015,respectively; in 2015,the non-point source nitrogen pollution was most serious in Wudi County and Huimin County and least serious in Zhanhua County; the non-point source phosphorus pollution was most serious in Zouping County and least serious in Wudi County.

Measurement and Evaluation of Ecological Environment Suitability in Binzhou City

Using entropy method and the urban ecological environment suitability index method,22 indicators were chosen from economic system,social system,and environmental system to measure and evaluate the suitability of urban ecological environment in Binzhou City during 2008-2015. The results showed that the suitability of urban ecological environment in Binzhou City was high overall from 2008 to 2015. It was at grade II in 2008 and 2009 and at grade I in the other years. The development level of economic and environmental systems was relatively high,and some indicators of social system had certain shortcomings.

Comprehensive Evaluation of Water Quality of Rivers in Binzhou Based on RAGA-PPCE Model

The water quality of main rivers in Binzhou City,Shandong Province was comprehensively evaluated based on RAGA-PPCE model. Six main factors such as ammonia nitrogen(NH-N),total phosphorus(TP),total nitrogen(TN),chemical oxygen demand(COD),dissolved oxygen(DO) and p H were used to establish the evaluation and classification standards of water quality. The results show that the evaluation results of water quality by RAGA-PPCE model and the fuzzy comprehensive evaluation method are basically the same. The evaluation results of RAGA-PPCE model are objective and reasonable and can be applied to the comprehensive evaluation of water quality.
