Spatiotemporal Evolution and Driving Forces of Urban Blue-Green Space Along the Yellow River——A Case Study of Tai'an City
摘要
Abstract
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 u-sing 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 km2,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 fragmen-tation of blue-green space showed a weakening trend,the landscape connectivity decreased and the land-scape 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 chan-ges was significantly greater than that of natural factors such as elevation.The study concludes that the sci-entific 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.关键词
