摘要
耕地是社会经济发展不可替代的自然资源,它大体决定了一地区的可持续发展能力。通过构造耕地产出效益系数、耕地污染替代系数、耕地消耗回报系数、耕地利用集约化系数指标,对咸宁市2002~2011年的耕地资源利用效益进行定量分析。结果表明:咸宁市耕地数量总体呈上升趋势,但是耕地质量却有所下降;同时耕地产出效益状况仅在2004、2006、2008年较好,其余年份内均较低,且有下降趋势。并针对性地提出提高咸宁市耕地资源利用效益的对策,以缓解人地矛盾的压力和农业发展困境。
In order to realize the status of cultivated land resources in Xianning and to protect cultivated land resources. Cultivated land utilization benefit was quantitatively analyzed according to output benefit coefficient,consumption and return coefficient, population and substitution coefficient and intensive cultivation coefficient in Xianning from 2002 to 2011. The results showed that: the quantity of cultivated land was upward trend in whole in Xianning,yet the quality of cultivated land was updown. At the same time,the output benefit of arable land was superior in 2004,2006 and 2008,but the rest of year was lower,and the tendency was dropping. On the basis of the results,the effectiveness of the strategies were improved to use of arable land resources.
