贵州省大方县农业生产系统可持续性分析

“可持续发展”虽然不再是一个新的概念，但在如何更好地保护和利用自然资源这个问题上，它依然是人们生活中所关注的一个热点。自从“可持续农业”概念的提出并成为社会的焦点以来．就存在着如何定义和衡量可持续农业的争论。目前广泛认同的一个观点就是农业的可持续发展包含着生态、经济、社会3方面的协调发展。根据大方县各生态区域的自然、社会和经济条件的不同，分别将小屯、竹园、六龙3个乡镇选为代表中低海拔、中海拔、中高海拔地区的生产状况，对大方县的农业生产的可持续性进行分析。根据所选的指标体系进行第一手资料和第二手资料搜集；农户调查通过面谈、田间观察和小组讨论进行。研究表明，从总体上来说，六龙镇的农业生产系统的可持续性在经济和社会方面稍好，3个乡镇的农业生产系统可持续性都属于中等水平；

SUSTAINABILITY ANALYSIS OF FARMING SYSTEMS IN DAFANG COUNTY GUIZHOU PROVINCE

Sustainability is not a new concept but rather a prominent one at present. Since sustainable agriculture became the watchword for capturing society's desire to better preserve the natural resource for future generations, there have been debates about how to define and measure sustainable agricultural systems. It is now widely agreed that there are different dimensions of sustainability ranging from the biophysical dimensions to economic and social dimensions. Sustainable agriculture at Dafang county was analyzed in terms of ecological sustainability, economic viability and social acceptability. Xiaotun, Zhuyuan and Liulong were selected as representatives of lower-middle, middle and middle-high agricultural areas of Dafang. Primary and secondary data were collected according to requirements of indicator evaluation. Household survey was carried out through interview, field observations and group discussion for the key information. The overall sustainability at Liulong is found to be slightly better than the other two sites in terms of economic viability and social acceptability. however, all three sites are considered as moderate sustainability in farming systems.
