摘　　要：本文以三江平原“黑土粮仓”——友谊农场为例,应用生态足迹法对当地的水土资源承载力进行定量评估。结果表明:(1)人均农业水资源生态足迹多年平均值为5.26 hm^(2)/人,生态承载力多年平均值为1.97 hm^(2)/人,水资源生态赤字,生态压力指数平均值为2.82,水资源利用处于不安全状态;人均耕地资源生态足迹小于生态承载力,耕地资源生态盈余,生态压力指数平均值为0.69,耕地资源利用处于安全状态;(2)友谊农场农业水土资源生态足迹和水土资源生态承载力的耦合协调度总体处于一般协调状态;(3)虽然农场土地资源丰富,但水资源稀缺,该地区的水土资源承载力协调水平还有很大的提升空间。研究结果对于黑土地保护,实现农业水土资源可持续发展有重要意义。The coordinated development of regional agricultural water and land resources is of great signific-ance to ensure agricultural production.However,the study on coupling evaluation of agricultural water and land resources is still insufficient.This article applies the ecological footprint method to quantitatively assess the carrying capacity of local land and water resources,taking the Youyi Farm of Sanjiang Plain,a scientific and technological demonstration area of the Black Earth Granary,as an example.The results showed that:1)The ecological footprint of per capita agricultural water resources was 5.26 hm^(2),and the ecological carrying capa-city of per capita was 1.97 hm^(2).The ecological footprint of per capita water resources was far more than the ecological carrying capacity.The ecological deficit of water resources was 2.82.The utilization of water re-sources was in an unsafe state.Per capita ecological footprint of cultivated land resources was less than the eco-logical carrying capacity,ecological surplus of cultivated land resources,the average ecological pressure index was 0.69.The use of cultivated land resources was in a safe state.2)The coupling coordination degree of the ecological footprint of agricultural land and water resources and the ecological carrying capacity of land and water resources of Youyi Farm is generally in the state of barely coordinated and primary coordination.3)In summary,although Youyi Farm was rich in land resources,water resources were scarce,indicating a signific-ant room for improvement in the level of water and land matching in the region.Analyzing whether the carry-ing capacity of agricultural water and land resources is within a reasonable and controllable range is of great significance for coordinating the relationship between agricultural water and land resources and realizing the sustainable development of agricultural water and land resources.
