Abstract：
Land use change stands as the primary factor influencing habitat quality (HQ). Clarifying the spatiotemporal change and the obstacle factors of the coupling relationship between HQ and urbanization level (UL) can provide imperative references for achieving sustainability in the Yellow River Basin (YRB). This study is based on the InVEST model, spatial autocorrelation, and obstacle factor analysis to measure the spatiotemporal dynamics and impediments of the coupling relationship between HQ and UL from 2000 to 2020 in the YRB. The findings were as follows: (1) From 2000 to 2020, the HQ showed a tendency of rise first and then fall, with the pattern of \"High in the middle and west, low in the east\"; (2) from 2000 to 2020, the UL had an upward trend, with the pattern of \"Low in the west, high in the middle and east\"; (3) the coupling and coordination level of HQ and UL in the YRB changed from extreme incoordination to verge of coordination, and it had a distribution pattern of \"High in the east, low in the west\", with the high-value area expanding to the east and the low-value area shrinking to the west. (4) Location condition, climate, proportion of construction land, vegetation index, and proportion of non-agricultural employment are the main obstacle factors that determined the coupling and coordination of the HQ and UL.
摘要：
土地利用变化是影响生境质量（HQ）的主要因素。厘清HQ与城市化水平(UL)耦合关系的时空变化和障碍因素,可为实现黄河流域可持续发展提供必要的参考。本研究基于InVEST模型，空间自相关，和障碍因子分析来测量YRB从2000年到2020年HQ和UL之间耦合关系的时空动态和障碍。研究结果如下:(1)从2000年到2020年,总部呈现出先升后降的趋势,具有“中部和西部高”的模式，东部低“；(2)从2000年到2020年，UL呈上升趋势，具有“西部低”的模式，中东部高”；（3）YRB中HQ和UL的耦合和协调水平从极端不协调转变为接近协调，它的分布模式是“东方高”，在西部低\“，高价值地区向东扩展，低价值地区向西缩小。(4)位置条件,气候,建设用地比例,植被指数,非农就业比例和非农就业比例是决定HQ与UL耦合协调的主要障碍因素。
