Influence Of Acid Rain On Agricultural Production In Anji

Abstract:Acid rain is the human activity on the earth to produce atmospheric pollution feature, is to measure the regional or national atmospheric pollution degree index. Acid rain on the earth’s ecosystems, human living environment constitute the serious harm of acid rain pollution, is currently the world attention to environmental problem. Acid rain into agricultural production environment, not only directly affect agricultural production, agricultural water and soil after entering, the pollutants also indirectly influence harm plant, animal, poultry fish plant and microbial growth, on agricultural ecological environmental threat, severe acid rain will lead to large area of forest decline and extinction of fish. Since2001the state environmental protection administration put forward two control zone" fifteen" key governance projects, acid rain control and prevention become the key problem of environmental protection of our country. Anji county is located in the northwest of Zhejiang Province, since2006, is the" acid" area, annual average value pH is less than4.5, the county’s acid rain rate is100%, and there has been no significant improvement. Through the study of acid rain to the local agricultural production, farmer life impact, in the acid rain control, reduce or even avoid the effects of acid deposition on agricultural production and proposed constructive suggestions.The main research contents:Based on the field investigation, data statistics and different types of crops in simulated acid rain acid rain experiment, according to the pH value of3,3.5,4,4.5,5each phase show different characteristics, combined with Anji County high rate of acid rain, acid rain pH average lower actual situation, to the county of acid rain on the main crop production and crop, Lin Mu fishery and the impact of the loss of a detailed, in-depth analysis. The acid rain on the local climate, agricultural economy, production and life brought adverse effect, find out the cause of acid rain and puts forward the corresponding solution measures.Main conclusions:l. Anji county is located in north of Zhejiang province Huzhou city county, belonging to the national " two controlled zones" heavy acid area. Due to the geographical location, climate and environment of industrial agriculture development level and other factors, Anji county from2006to2010, there has been heavy acid.2. Effect of acid rain, the traditional crop in production and yield have appeared different degree of reduction of output, serious or even crops, to traditional agriculture production brought a certain economic losses.3. In the county forest, herd, fishery of acid rain to bring different influence, harm the environment of agricultural production, which hinders the agricultural development.4. acid rain makes part of agricultural crops, farmers’enthusiasm drops, agriculture to engaged in non-agricultural sectors of the population gradually increased, some traditional agricultural labor loss.5. The government of the acid rain control propaganda is low, local farmers to acid rain generally low awareness, awareness of environmental protection is weak, in agricultural production process ignored in the acid rain control.The countermeasures and suggestions:Strengthen supervision and management, always in control of industrial waste emissions; adjusting energy structure, improving combustion technology; to" Dazhi small" namely from industrial big grabs cure; to" prevention", strengthen heavy acid area surrounding provinces to acid rain pollution control; to strengthen the supervision and management of motor vehicle emissions; adjustment of agricultural planting structure, screening and cultivation of acid-fast ability of agricultural products, reduce agricultural economic loss; planting acid absorption ability of the forest remission of acid rain on soil pollution of acid rain; construction of buffer facilities, reduce agriculture forestry animal husbandry and fishery economic loss; balance of animal husbandry development speed, do good stock raising health management propaganda and popularization of knowledge of prevention and control of acid rain;to reduce acid rain to bring local farmers agricultural economic loss.
