摘　　要：城市扩张侵占生态空间,带来生态空间破碎化、生态系统服务能力持续下降、生态环境问题频发等一系列问题,是导致城市人地关系失调的主要原因,保护与修复城市生态空间是实现人地关系协调的必然途径。山地城市生态空间占比大、地形复杂,协调人地关系面临更多挑战。在生态智慧的引领下,基于生态梯度分析构建生态空间保护与人地关系协调的逻辑与实践框架。以南水北调中线上重要的山地城市--十堰市为例,分析生态问题并诊断生态空间破碎化为根源,整体性保护主要生态要素和核心生态功能,识别其中人类活动干扰空间和潜在威胁空间,划定多梯度保护与修复格局并提出相应的实践导则,协调城市发展中的人地关系矛盾,实现可持续发展。Urban expansion encroaches on the ecological space. It has led to fragmentation of ecological space and continuous decline of the ecosystem service capacity, giving rise to a series of ecological environment problems, which is the main reason for the imbalance of urban human-land relationship. Protecting and repairing urban ecological space is the only access to coordination of the human-land relationship. The proportion of ecological space in mountainous cities is large and the terrain is complex. Thus the coordination of humanland relationship faces greater challenges. Under the guidance of the ecological wisdom and based on ecological gradient analysis, this paper constructs a logical and practical framework to coordinate the human-land relationship through ecological space protection, aiming at multi-level protection of ecological space based on the ecological gradient. Taking Shiyan City, an important mountainous city on the middle line of the south-to-north water diversion project, as an example, this paper analyzes the ecological problems in the city and diagnoses the root cause as the fragmentation of the ecological space. The main ecological factors and core ecological functions are protected as a whole, and the spaces threatened by human activities are identified. Finally, this paper defines the pattern of multi-gradient ecological protection and puts forward corresponding practical guidelines to coordinate the contradiction between man and land in urban development for sustainable development.
