摘要
为避免在权重确定过程中忽略指标间相互影响的情况,增加权重的科学合理性,文中引入网络分析法确定权重,更加科学地对陕西省耕地集约利用水平进行分析。研究表明陕西省耕地集约利用水平整体提高,城市间耕地利用集约度差异明显;空间上呈现陕西关中平原区耕地利用集约度较高,南部秦巴山区及陕西北部高原区耕地利用集约度较低的特征;陕西省耕地集约利用趋势呈现由平原向山区,以西安市和杨凌示范区为中心,渐次向外扩展的态势。
In the process of determining the weight,the interaction between the indicators is often neglected.In order to increase the scientific rationality of determining the weight,the Analysis Network Process was introduced to determine the weight,and evaluate the intensive utilization degree of cultivated land in Shaanxi province.The results show that the level of intensive use of cultivated land in Shaanxi province was increasing year by year,and the differences of intensive use of cultivated land among cities were obvious.The intensive use of cultivated land in Guanzhong Plain of Shaanxi province was relatively high,while the intensive use of cultivated land in southern Qinba Mountains and Northern Shaanxi Plateau was relatively low.The intensive use of cultivated land in Shaanxi Province was expanded from plain to mountainous area,from center zones such as Xi’an City and Yangling Demonstration to the surrounding areas gradually.
