摘要：In response to the urgent requirements of urban construction and ecological protection, the ecological assessment research of urban landscape planning and design aims at establishing an assessment model and index system with unified ecological assessment scale, with a view to providing clear and comparable ecological assessment results, providing scientific basis and technical support for the management decisionmaking of landscape planning, and providing a basis for the evaluation and modification of the scheme and optimization. Combining with the systematic characteristics of urban landscape, this paper proposes a horseshoe-shaped urban landscape design research idea based on two -dimensional numerical analysis for the first time, establishes a basic evaluation model with ULEE as the core standard and EF as the unified measure, and discusses the key points and research framework of further research. In order to solve the contradiction between the simplicity and objectivity of ecological assessment methods, a useful attempt was made in theoretical research, hoping to benefit the study of ecological sustainability in the field of planning and design.
