【目的】避暑山庄作为当今存世的最大皇家园林,因经典的自然山水营构而享有盛誉。自1703年始建至1911年清朝覆灭,避暑山庄内外水系面貌发生了剧烈的变化,然而水系变迁成因尚缺乏全面而深入的探究。【方法】梳理避暑山庄肇建后200余年间的水系面貌变迁历程,利用史料梳理论证与量化计算佐证相结合的方法,聚焦避暑山庄内外水系营建的历史过程,分析山庄引水工程、扩湖工程及河工制度存废对于水系带来的反向制约影响;以历史图档、文档记载为基础,以20世纪80年代最早期的土地利用/土地覆盖遥感监测数据及同时期的承德地区土壤流失情况为依据,从流域层面探讨了武烈河河道泥沙的来源问题。【结果】避暑山庄肇建之初设定的引水点为河流交汇口区域,频繁的河相变化增加了山庄引水困难;康熙朝施行的扩湖工程,使得山庄东侧的武烈河行洪断面缩减超过50%;围绕避暑山庄展开的“旱河岁修”“河湖清挖”“大河岁修”等制度的订立、完善与废弃历程耦合着山庄内外水系急剧变迁的过程;清晚期以来,武烈河流域内土地滥垦日益严重,1980年流域内的坡耕地产生的土壤流失总量(1025422.30 t)与同时期武烈河流域年平均输沙量(1070000.00 t)接近。【结论】避暑山庄的水系营建工程虽然造就了经典的水景观,但也助推了山庄水系的消退,而晚清以来武烈河流域内坡耕地过垦所带来的水土流失问题,则是造成避暑山庄内外水系变迁的最关键性因素。避暑山庄内外水系变迁成因的历时性考察,是景观遗产多元价值识别的前提,也是挖掘、培育生态智慧的必由之路。
