- 摘要:
- 为了分析关中地区农业水土资源的时空匹配情况，应用农业水土资源匹配系数，评价了关中地区及所辖5个地级市的农业水土资源匹配程度。结果表明：关中地区水资源短缺、人水矛盾和人地矛盾突出；农业水土资源匹配格局的时间变化不明显，而空间匹配存在明显的差异，宝鸡市和西安市的匹配程度优于其他市区，咸阳市的匹配程度最差。因此，应该通过跨流域调水工程、提高有效灌溉面积、改进农业结构等措施，提高关中地区农业水土资源的匹配程度。
- Abstract:
- In order to analyze the spatial-temporal match pattern of agricultural water-land resources in Guanzhong area, agricultural water-land resources match coefficient was used to evaluate the match degree of agricultural water-land resources of Guanzhong area and the five prefecture-scale regions in this area. Results showed that water resources were short with significant human-water and human-land conflict. In addition, temporal variation of agricultural water-land resources match was not evident, spatial match, however, existed great variation. Baoji City and Xi’an City had a higher match degree than other cities, and Xianyang City had the lowest match degree. Consequently, agricultural water-land resources match degree in Guanzhong area may be improved by introduction of inter-basin water transfer projects and increasing water-land utilization and strengthening water-land resources protection practices.
