摘要:
干旱区内耕地急剧扩张导致水资源严重超载,进而引发一系列生态问题,因此对干旱区绿洲耕地适宜规模进行科学评估,将为干旱区农业可持续发展与生态保护提供重要参考。本文以水资源为约束条件,选择2000年、2005年、2010年、2015年和2018年5个研究时段,分别测算了适宜当地社会经济发展和生态环境需求的“三生”用水量;并基于绿洲水热平衡原理,耦合作物种植结构、不同生长期内的作物系数以及灌溉保障率、耕地覆膜等因素,构建了干旱区耕地水热平衡估算模型,探讨了不同情景下新疆昌吉州耕地适宜规模及其超载程度。结果表明,5个时段中,临界耕地适宜规模情景下的种植业可用水量由2000年的31.75亿m3波动下降至2018年的24.83亿m3,而最佳耕地适宜规模情景下则由27.63亿m3波动下降至21.10亿m3。棉花和小麦在当地种植业结构中占比之和由43.58%提高到2018年的59.08%,两种作物的低耗水特性使其种植占比的提高有利于当地种植业向耕地规模扩张的方向演进。各时段中,保障充分生态用水的最佳耕地适宜规模在28.93万~48.97万hm2间波动,而保障最低生态用水的临界耕地适宜规模在42.63万~67.83万hm2间波动。虽然两种用水情景下的适宜耕地规模波动变化,但耕地面积超载程度始终呈上升趋势,超载程度分别由2000年处于不超载水平的-55.15%和-39.41%提高到2018年的接近于严重超载级别的19.92%和远超严重超载级别的71.37%,表明当地耕地规模已明显呈现过度开发的趋势。
