An integrated approach for Territorial Spatial Planning Towards to Sustainable Urban Ecosystem Management: A Case Study of Yantai City

Abstract

<p> With the rapid urbanization, the most challenges have been faced with the accelerated degradation of habitat quality and increasing ecological risks for urban natural ecosystems. It is important to explore an integrated approach for territorial spatial planning towards to sustainable urban ecosystem management for directing programs of natural ecosystems conservation and restoration toward preserving the most valuable natural resources. In the study, Yantai city in Shangdong province in China was as an example. The goal, method and spatial boundary of territorial spatial planning towards to sustainable urban ecosystem management were clarified. A technical framework of urban territorial spatial planning and an integrated approach to determine key areas of ecosystem preservation and restoration were proposed. The results showed that the application of urban territorial spatial planning in Yantai was feasible and effective and provided new ideas and methods for the territorial spatial planning. The ecological network pattern by the “two horizontal and two vertical” spatial pattern was proposed. Key areas of ecosystems conservation and restoration were identified, including 13 ecological pinch points, 8 ecological barrier points, 39 ecological break points, and 1308.66 km<sup>2</sup> fragmented ecological land. Natural solutions and measures for key areas of ecosystems conservation and restoration were proposed. It would help to provide scientific guidance for urban spatial planning toward to sustainable ecosystem management.</p>
