摘要
基于2000-2020年土地利用类型数据,采用景观指数、景观动态度、地理探测器等方法,分析沿黄城市泰安市蓝绿空间时空演变特征及其驱动因素。结果表明,1)近20 a泰安市蓝绿空间规模整体呈减少趋势,动态度为-0.41%,面积减少131.24 km 2,但呈现明显的阶段性特征,前10 a变化剧烈,动态度为-0.82%,后10 a动态度仅为0.005%。2)2000-2020年,蓝绿空间景观格局指数发生了显著变化,且各指数在前10 a的变化程度更大;类型水平上,绿色空间和蓝色空间的景观形状整体趋于规则、均有连片发展趋势,但绿色空间的景观形状更复杂、分布离散度更大;景观水平上,蓝绿空间破碎度呈减弱趋势,但景观连通性下降、景观异质性增强。3)地理探测分析表明,社会经济因素是蓝绿空间分异的主导因子,生产总值、人口密度、第一与第二产业产值等社会经济因素对蓝绿空间变化的解释力显著大于高程等自然因素。研究认为城镇化进程中需要加强对国土空间的科学管控,应加强泰安市蓝绿空间的完整性、连通性保护。该研究为泰安市蓝绿空间优化与管理、区域可持续发展提供一定参考。
Based on the land use type data from 2000 to 2020,the spatiotemporal evolution characteristics of blue-green space and its driving factors in Tai an City,a city along the Yellow River,were analyzed by using landscape index,landscape dynamic attitude and geographical detector tool.The results showed that 1)the scale of blue-green space in Tai an City had been decreasing overall in the last 20 years,with a kinetic attitude of-0.41%and an area of 131.24 km 2,presenting obvious stage characteristics.The change was dramatic in the first 10 years,with a-0.82%dynamic attitude,and only 0.005%in the second 10 years.2)From 2000 to 2020,the blue-green spatial landscape pattern index changed significantly,and the indices changed more in the first 10 years.At the type level,the landscape shape of green space and blue space as a whole tended to be regular and both had the development trend of contiguity,but the landscape shape of green space was more complex and the distribution was more discrete.At the landscape level,the fragmentation of blue-green space showed a weakening trend,the landscape connectivity decreased and the landscape heterogeneity increased.3)Geographical detection analysis showed that socio-economic factors were the dominant factors of blue-green spatial differentiation.The explanatory power of socio-economic factors such as GDP,population density,primary and secondary industry output values on blue-green spatial changes was significantly greater than that of natural factors such as elevation.The study concludes that the scientific control of land space needs to be strengthened in the process of urbanization,and the integrity and connectivity of blue-green space in Tai an City should be protected.This research provides some reference for the optimization and management of blue-green space and sustainable development of the region in Tai an City.
