三生空间融贯理念下的县城景观提质设计——以无定河流域绥德县为例
County Landscape Quality Improvement Design under the Concept of Living-Production-Ecological Space Integration—Taking Suide County in Wuding River Basin as an Example

依据存量更新大背景，响应国家“大力推进县城提质增效，改善县城人居环境”的要求，立足绥德县特殊的地形地貌、地域气候、发展状况等特征；本文围绕“县城更新”利用景观生态学相关原理和数据统计等方法分析绥德县近年来景观格局变化情况。研究结果表明：绥德县近10年景观多样性指数保持稳定且水域景观优势度一直处于最高位置说明县城发展改造较慢，绿地建设水平较低，县城更新力度及速度都有待提高且水域空间在县城景观营造中占绝对优势。故以县城滨河廊道的地域性重构为主要媒介探讨黄土高原河谷型县城景观风貌优化策略以期为绥德县可持续发展及高质量人居环境建设提供思路。
Based on the background of stock updating and in response to the national requirements of “vigorously promoting the improvement of quality and efficiency of county towns, and improving the living environment of county towns”, based on the special terrain, regional climate, development status and other characteristics of Suide County. This article analyzes the changes in landscape pattern in Suide County in recent years based on the principles of landscape ecology and data statistics, focusing on “county town renewal”. The research results indicate that the landscape diversity index of Suide County has remained stable in the past 10 years and the dominance of water landscape has always been at the highest position, indicating that the development and transformation of the county town is slow, the level of green space construction is low, and the intensity and speed of county town renewal need to be improved, and the water space occupies an absolute advantage in the county town landscape construction. Therefore, the regional reconstruction of the riverside corridor in the county town is used as the main medium to explore the optimization strategies for the landscape style of the loess plateau valley-type county town, in order to provide ideas for the sustainable development and high-quality human settlement environment construction of Suide County.
