Based on the analysis of the connotation of the effect of territory ecological restoration and urbanization development,this paper constructed the evaluation index system,and used fuzzy evaluation,coupling coordination,panel vector autoregression and spatial Durbin model to measure the interaction and spatial linkage effects of ecological restoration of national land space and urbanization de-velopment effect in 31 provinces from 2005 to 2020.The results showed that:①The territory ecological restoration index increased from 0.179 to 0.740,showing"Central＞East＞Northeast＞West".The urbanization effect index increased from 0.134 to 0.833,showing"East＞Central＞Northeast＞West".②The coupling coordination degree increased from 0.394 to 0.886,and changed from mild mal-adjustment to good coupling coordination,showing"Central＞Eastern＞Northeast＞Western".③The explanatory power of national terri-tory space ecological restoration to its own and urbanization development effects was 60.9%and 15.6%respectively,and the explana-tory power of urbanization effect to its own and national territory space ecological restoration was 84.4%and 39.1%respectively.④The spatial regression coefficient of territory ecological restoration was 0.148,the direct effect of urbanization on territory ecological res-toration was 0.221%,and the spatial spillover effect was 0.071%.The effect of urbanization development had a greater explanatory power to the territory ecological restoration,and there was a good time series coupling coordination between them.The development effect of urbanization had a significant positive spatial spillover effect on the territory ecological restoration,and there was an unequal role and a spatial linkage development of reaction between them.
