摘　　要：基于浙江省1980—2020年8期土地利用数据,分析了浙江省不同时期水域系统时空格局、水面率、转换趋势、景观格局等特征,揭示了水域系统面积变化的驱动因素。结果表明:(1)浙江省水域面积总体呈增加趋势,河流、滩地面积缩减,湖泊、水库坑塘、滩涂面积增加。水域系统转移集中于河流、湖泊和沿海一侧。(2)浙江省水域景观格局MPS、NP、LST、FRA、CCONTAG指数上升,PD、ED、LPI、COHESION、AI指数下降,突出反映了水域景观破碎化、离散化、复杂化。(3)不同地级市水域系统面积存在差异,杭州市的河流、水库坑塘面积最大,嘉兴市和湖州市的湖泊面积最大,宁波市的滩涂面积最大,绍兴市的滩地面积最大。各流域水域系统大多以水库坑塘为主,面积呈增加趋势,其他地类面积变化较小。(4)浙江省水域系统与人为活动(GDP、农林牧渔总产值、人口密度)关系密切,自然因素对水域影响较为稳定,年均降水量的影响大于年均温度的影响。Based on the land use data in Zhejiang province of 8 periods from 1980 to 2020, this study analyzed the water system spatiotemporal pattern, water surface ratio, transformation trend, landscape pattern and other characteristics in different periods of Zhejiang province, trying to reveal the driving factors of these changes. The results show that:(1)the total water area of Zhejiang province tends to rise, the area of rivers and beaches tend to decrease, while the area of lakes, reservoirs, ponds and tidal flats tend to increase. The transfer of water system was concentrated in rivers, lakes and coastal side.(2) The water landscape pattern index of Zhejiang province increase by MPS, NP, LST, FRA,CCONTAG, and decrease by PD, ED, LPI, COHESION and AI, reflecting the fragmentation, dispersion and complexity of water landscape.(3) The area of water system shows different pattern in different cities, in particular, the area of rivers, reservoirs ponds in Hangzhou is the largest, the area of lakes in Jiaxing and Huzhou is the largest, the area of tidal flats in Ningbo is the largest, the area of beaches in Shaoxing is the largest. The water system of each basin mainly consists of reservoirs and ponds, and their area were increased during these periods, while the area of other land types changed little.(4) The water area system of Zhejiang province was closely related to human activities(GDP, total output value of agriculture, forestry, animal husbandry and fishery, population density), while the influence of natural factors on water area was relatively stable with the influence of annual precipitation greater than that of annual temperature.
