An evaluation of the spatial rationality of provincial territory: a case study of Gansu Province

In China, utilization and evaluation of territorial space have become national strategic issues. Evaluating the rationality of urban, ecological, and agricultural space is significant in the development of territorial space and provides a theoretical basis for the optimization of provincial territorial space. The strategic positioning of Gansu Province as a national ecological environment safety barrier is significant to the protection of the ecological environment of northwest China. This study used the entropy method to evaluate the rationality of territorial space development in 14 cities in Gansu Province in 2019, using 50 indicators of urban, ecological, and agricultural space. Results reveal that in the evaluation of these three spaces, the most important influencing indicators are water supply penetration rate, proportion of desert area, and proportion of agricultural population, respectively. In the total evaluation of territorial space rationality, the city with the highest comprehensive index is Qingyang (2.0521), followed by Zhangye (1.5635), while Lanzhou (1.1553) has the lowest evaluation. In Gansu, cities with the best territorial spatial conditions are concentrated in the east, whereas those with poor territorial spatial environmental security are located in central Gansu and the Hexi Corridor. Collectively, these findings suggest that the equity and rationality of urban, ecological, and agricultural space in territorial space should be considered in territorial space planning strategies. The balance and harmony of these three spaces play a positive role in the sustainable development of the economy, society, and the environment in urban areas.
