Beidaihe is a district under the jurisdiction of Qinhuangdao and is a famous seaside scenic area. Alliance Peak, located in Beidaihe seashore scenic West. Jinshan mouth is the peak of the Union Peak, located in the easternmost Beidaihe waterfront. In this paper, we use the observed data of air negative ions in the Beidaihe, Qinhuangdao, Jinshanzui and Lianfeng Mountains for seven years to study the distribution characteristics of negative air ions in different ecological environments through meteorological observation. Research shows that the annual mean of air anion concentration fluctuates less. The annual mean is 1730 ind·cm-3, and the difference between the highest and lowest concentrations is 535 ind·cm-3. The average air anion concentration was the highest in August at 7785 ind·cm-3 and the lowest in January at 365 ind·cm-3. Negative air ions have obvious spatial characteristics, and negative ion concentrations of the sea and forest air are significantly high. The average annual mean of the sea is 3902 ind·cm-3, and that of the forest is 5403 ind·cm-3. The concentration of air anion changes daily, and daytime concentration is significantly lower than nighttime concentration. The highest peak appears at night or in the morning, while the lowest value appears between noon and afternoon. Inter-annual features and concentration of negative air ions, as well as annual rain days, total rainfall, thunderstorm days, and average relative humidity, are negatively related to the annual average temperature and sunshine hours. However, in the average concentration of negative air ions, the average correlation test of meteorological elements was insignificant. The air anion concentration is negatively correlated with the PM2.5 concentration of fine particulate matter. The concentrations of nitrogen dioxide, sulfur dioxide, and carbon monoxide in the fine particulate matter are negatively correlated with the ozone concentration, which is positively correlated with ozone concentration and is tested by significance. Atmospheric discharge (thunderstorm) can produce a considerable amount of air anion. Air negative ions are an important indicator of air quality, which is of great significance to the living environment. The distribution of negative ions in the study space and its influencing factors in order to provide a basis for air quality assessment in the region and provide references for the long-term research on air anion in different urban areas.展开更多

文摘In this paper, CVM method (conditional value evaluation method, also known as willingness investigation method) is used to investigate the willingness to pay about the ecological environment protection cost of Shaanxi Huashan scenic spot in July and August, 2013. By establishing the Logistic regression model, the per capita willingness to pay (WTP) of the tourists is calculated to be 79.2 yuan / person. The results show that the tourists' awareness of environmental protection is increasing day by day, and the visitors are fully aware of the importance of protecting the ecological environment. 57.85% of the tourists will be willing to pay, including civil servants, self-employed persons, college degree or above, family monthly income in the 8000-10000 yuan visitors will pay higher. This provides a reference for the sustainable development and development of ecotourism in Huashan Scenic Spot.
文摘With the establishment of environmental protection system,protecting the ecological environment and reducing the use of energy consumption have become the mainstream idea in the development structure of green buildings.In the university construction projects,we must also uphold the principle of improving the ecosystem of colleges and universities,and strengthen the level of energy conservation and consumption reduction,to achieve a win-win situation in ecological civilization and university building management.This paper analyzes the value of green building in the ecological environment of colleges and universities and discusses the specific application and application path,for reference only.
文摘Qinhuangdao is a provincial municipality under the jurisdiction of Hebei Province and a coastal city in China. Beidaihe is a district under the jurisdiction of Qinhuangdao and is a famous seaside scenic area. Alliance Peak, located in Beidaihe seashore scenic West. Jinshan mouth is the peak of the Union Peak, located in the easternmost Beidaihe waterfront. In this paper, we use the observed data of air negative ions in the Beidaihe, Qinhuangdao, Jinshanzui and Lianfeng Mountains for seven years to study the distribution characteristics of negative air ions in different ecological environments through meteorological observation. Research shows that the annual mean of air anion concentration fluctuates less. The annual mean is 1730 ind·cm-3, and the difference between the highest and lowest concentrations is 535 ind·cm-3. The average air anion concentration was the highest in August at 7785 ind·cm-3 and the lowest in January at 365 ind·cm-3. Negative air ions have obvious spatial characteristics, and negative ion concentrations of the sea and forest air are significantly high. The average annual mean of the sea is 3902 ind·cm-3, and that of the forest is 5403 ind·cm-3. The concentration of air anion changes daily, and daytime concentration is significantly lower than nighttime concentration. The highest peak appears at night or in the morning, while the lowest value appears between noon and afternoon. Inter-annual features and concentration of negative air ions, as well as annual rain days, total rainfall, thunderstorm days, and average relative humidity, are negatively related to the annual average temperature and sunshine hours. However, in the average concentration of negative air ions, the average correlation test of meteorological elements was insignificant. The air anion concentration is negatively correlated with the PM2.5 concentration of fine particulate matter. The concentrations of nitrogen dioxide, sulfur dioxide, and carbon monoxide in the fine particulate matter are negatively correlated with the ozone concentration, which is positively correlated with ozone concentration and is tested by significance. Atmospheric discharge (thunderstorm) can produce a considerable amount of air anion. Air negative ions are an important indicator of air quality, which is of great significance to the living environment. The distribution of negative ions in the study space and its influencing factors in order to provide a basis for air quality assessment in the region and provide references for the long-term research on air anion in different urban areas.

文摘The integrated development of Tibet "one river and two streams" agricultural ecological basin should control the generated environmental problems and prevent new environmental problems,thereby promoting coordinated development of agricultural economy in the region. It is very necessary and urgent to explore main environmental problems of Tibet " one river and two streams" agricultural ecological basin and effective countermeasures. When developing resources and economy,the principle of combining prevention with control,dominated by prevention and integrated control should be followed; regional advantages,characteristics and environmental self restoring ability should be sufficiently played and used; the policy of integrated prevention and utilization should be used; compensation method,prevention control measures and planning assumption for main environmental problems should be proposed,which could prevent that systemic development of Tibet " one river and two streams" agricultural ecological basin takes the old path of " firstly destroying and then controlling".
