摘　　要：基于NDVI、LSWI、土地利用数据以及气象和统计数据,借助CASA-VPM模型和生态经济协调耦合度模型分析了黄河流域2001-2018年植被NPP时空分异特征;探讨了生态和经济发展现状,并以此对生态经济协调耦合度做出评价。结果表明:2001-2018年黄河流域植被NPP年平均值为288.33 gC/(m^(2)·a),且持续波动增加,空间上呈现出南高北低,平原、盆地高,高原、山地低的分布特征;不同植被类型月平均NPP变化呈现出周期性单峰型变化的特征且不同植被类型随时间变化的趋势和周期相同,但变化幅度和变化速率具有明显的区分度;研究区年总生态价值和经济价值拟合后分别呈现出“U”型和线性的变化特征,且后者增长速率远大于前者,空间上冷点区主要分布在西北部山地与高原边缘过渡地区,热点区域则主要位于黄河流域的“金三角”地带;研究区生态经济协调耦合度呈现出“大分散,小聚集”的条带状空间分布特征且以“W”型曲线不断上升,经济发展水平是流域生态经济协调耦合度的主导因素。The spatial-temporal differentiation of the vegetation NPP in the Yellow River Basin from 2001 to 2018 was analyzed with CASA-VPM model and ecological economic coordination coupling degree model based on NDVI,LSWI,land use data,meteorological data and statistical data.The current ecological and economic development status is discussed.The degree of ecological-economic coordination and coupling is evaluated.The results showed that the annual average vegetation NPP in the Yellow River Basin from 2001 to 2018 was 288.33 gC/(m^(2)·a).The fluctuations are continued to increase.The spatial distribution characteristics of the NPP are high in the south and low in the north,high in the plains and basins,and low in the plateaus and mountains.The monthly average NPP change of different vegetation types has the characteristics of periodic single-peak changes.The trends and cycles of different vegetation types over time are the same,but the amplitude and rate of change has obvious distinction.The total annual ecological value of the area studied after the economic value is fitted with“U”-shaped and linear change characteristics,with the growth rate of latter much higher than that of the former.The cold spots are mainly distributed in the transitional area between the northwestern mountain and the plateau edge.The hot spots are mainly located in the Yellow River,the“Golden Triangle”area of the river basin.The ecological and economic coordination coupling degree of the area studied presents a strip-like spatial distribution characteristic of“large dispersion,small aggregation”and rising with a“W”curve.The level of economic development is the dominant factor for the ecological and economic coordination coupling degree of the river basin.
