摘要
运用可持续发展度评价模型,对黄土丘陵区川道地农业生态系统可持续发展水平进行了分析,结果表明:经过多年的退耕还林还草与农业结构调整,研究区农业生态系统生态发展位、经济发展位、社会发展位及综合发展位均有不同程度的提升,社会、经济发展水平不断提高,生态环境明显改善。经济发展势、社会发展势在波动中上升,生态发展势与综合发展势在调查年度内呈降低趋势。系统协调度与可持续发展度逐年增加,表明研究区农业系统实现了经济增长、社会进步与生态环境改善协调发展,可持续发展能力逐渐增强。
Sustainability assessment of agro-ecosystem in hilly gully region of Loess Plateau was carried out by using sustainable development degree model in this paper.Ecological,economic,social development location and integrative development location all presented rising trend to different extent by regulating agricultural instructure and conversion of cultivated land to forest or grass.Which indicated that the development level of society and economy increased,ecolgical environment was improved evidently year by year.Development potentials of economy and society rose fluctuantly.By contrary,ecological development potential and integrative development potential decended on the whole during 1996-2006.Moreover,economy,society and ecological evenvironment were harmoniouly improved,sustainable development level boosted up little by little due to harmonious degree and sustainable development degree rising grandually.
