摘　　要：论文利用GIS空间分析技术,以闽侯县上街镇为例,从空间实际距离和时间成本角度对畜禽养殖废弃物养分农用地施用可达性进行了分析,并以耕地氮、磷负荷限量标准计算了不同空间距离段和时间段农用地的氮、磷养分消纳潜力.研究结果表明,研究区90.18%的农用地空间可达距离在5 000 m内,其中平均空间可达距离为2 330 m.88.26%的农用地时间可达性在10 min内,其中平均时间可达性为5.09 min.该研究可为畜禽养殖废弃物的返田合理利用提供科学依据.The paper analyzes accessibility of applying livestock manure to farmland from the perspective of spatial distance and time cost taking Shangjie town in Minhou County as example based on spatial analysis techniques of GIS. Then potential treatment ability of nitrogen and phosphorus nutrients are calculated in different section of spatial distance and time in limit standard of nitrogen and phosphorus loading of farmland. The results show that the average distance of the accessibility analysis of application livestock manure to farmland is 2 330. 436 m and 90. 18% of farmland not exceeds5 000 m. The average time of the accessibility analysis of application livestock manure to farmland is5. 09 minutes and 88. 26% of farmland not exceeds 10 minutes. The results can provide scientific basis for reasonable use of livestock manure.
