摘要:
以江西赣州市18个县(市、区)为研究对象,从自然、社会、经济三个方面共选取了18项指标构建赣南地区农业生态系统脆弱性评价指标体系。采用熵权法确定各指标权重; 运用综合指数法计算出各县(市、区)生态脆弱度的值并进行分级; 运用主成分分析法,探讨该区域农业生态系统脆弱性的主要驱动力。结果表明:(1)赣南地区农业生态系统脆弱性以中度和轻度脆弱为主。其中,极度脆弱县有1个,高度脆弱县有2个,中度脆弱县有4个,轻度脆弱县有8个,微度脆弱县有3个,极度脆弱区、强度脆弱区、中度脆弱区、轻度脆弱区和微度脆弱区分别占全区总
Abstract:
Gannan District is the primary district of producing grain,oil,wood and fruits in Jiangxi Province.It is also one of the most serious soil erosion districts in Southern China.Its ecological vulnerability is very obvious.The study on the vulnerability of agricultural ecosystem will play an important role in protecting environment and reasonable use of resources,and has guiding significance for the restoration and reconstruction of agricultural ecosystem and the development of agricultural modernization.Taking 18 counties(city and divisions)of Gannan as the research objects,this paper selects 18 indicators to build up the agricultural ecosystem vulnerability evaluation index system from three aspects of nature,society and economy,uses the entropy weight method to determine the weight of each index,uses the comprehensive index method to calculate the county(city,district)ecological vulnerability value and classification,and the principal component analysis was used to study the main driving forces of the vulnerability of agricultural ecosystem in this region.The results show that:(1)the agricultural ecosystem vulnerability in Gannan District is mainly mild to moderate and fragile.Among them,there are 1 extremely vulnerable county,2 highly vulnerable counties,4 moderately vulnerable counties,8 slightly vulnerable counties,3 micro vulnerable counties,extremely vulnerable regions,highly vulnerable regions,moderate vulnerability regions,mild vulnerability regions and slightly vulnerable regions respectively accounted for 9.2%,12%,28.8%,39.7% and 10.3% of total District of the whole region;(2)the main driving force of the vulnerability of agricultural ecosystem in this District respectively is the economic development and agricultural input,topography and soil erosion situation,climate conditions,the living standards of farmers and agricultural non-point source pollution,and water conservancy construction.Among them,the economic development and agricultural investment are the main driving forces.
