Abstract:
Objectives Gaizhou City and Bayuquan District, situated in the southern reaches of Yingkou, occupey a pivotal position in the regional landscape. They serve as vital gateways, linking the Shenyang metropolitan area with the Liaodong Peninsula, and represent important nodes within the broader coastal economic zone. Along with economic development, ecological protection has become increasingly important. Ecological corridors play a crucial role in improving landscape connectivity and enhancing the stability of ecosystems. In order to better serve economic development and promote green and sustainable development in the southern part of Yingkou, it is necessary to construct a certain number of natural ecological corridors in the southern part of Yingkou to form a stable ecological pattern.
Methods This article employed a morphological spatial analysis (MSPA) approach, integrated with a minimum cumulative resistance model (MCR), to delineate an ecological corridor in the southern region of Yingkou. The scientific merit of this corridor was then evaluated through a corridor network connectivity analysis. In light of these findings, recommendations were put forth for the construction of the ecological corridor in the southern part of Yingkou.
Results (1) The total area of important ecological source areas in the southern part of Yingkou is 11.6 km2. (2) The ecological network construction in the southern part of Yingkou is relatively concentrated, with generally similar properties. Furthermore, the ecological source areas that are closer exhibit greater interaction forces. (3) The width of the biological corridor in the southern area of Yingkou is greater than 800 meters, and the width of the river corridor is determined in three levels: 80-100 meters, 30-60 meters, and 10-30 meters. The width of the initial two levels of production production and living connecting roads has been determined to be 60-200 meters, while the width of the third level has been set at 20-60 meters.
Couclusions On the basis of identifying important ecological source areas within the region, this article employed the method of constructing ecological resistance surfaces and minimum cost paths to select important ecological corridors. This approach provided crucial support for the construction of ecological security patterns and the enhancement of the ecological environment in the southern part of Yingkou. The methodology and practical applications of this approach wereof significant value.
