摘要
以天水市麦积区为例,从自然质量条件、工程建设条件、景观生态条件3方面,选取评价建设高标准农田建设时序的关键性指标,提出"整体参与综合评价、耕地质量存在差异、工程建设先易后难"的建设时序评价原则,并结合综合评价系数法及自然断点法确定麦积区高标准农田建设时序。结果表明,麦积区高标准农田建设时序近期、中期、远期整治区面积分别占区内耕地总面积的17.54%、51.87%、30.59%。研究结果可为麦积区及丘陵沟壑区高标准农田建设安排和政府决策提供借鉴。
In the present study, Maiji District, Tianshui City was taken as an example, and key evaluation indicators were selected from aspects of natural quality conditions, engineering construction conditions and ecological landscape conditions. The construction sequence evaluation principle was proposed as aoverall comprehensive evaluation, culti-vated land quality vary, and easy projects first”. By comprehensive evaluation coefficient method and natural break method, the construction sequence in Maiji District was evaluated, and reasonable arrangements for the construction mode were proposed. The results showed that the construction scale in the near, medium and long-term should be 17. 54% , 51. 87% , 30. 59% , respectively. These results could provide references for the excellent-criterion farm-land construction in Maiji District and the loess hilly and gully region.
