Hydrologic Spatial Performance Analysis Of Yu-Jia Traditional Village Based On Theories Of LPS

Since the "Central Urbanization Work Conference" at the end of 2013 launched the Sponge City for the national strategy,China has set up two batches of a total of 30 sponge city pilots,and the construction of the sponge city is developing rapidly at present.However,the problems of Urban Waterlog in our country still occur occasionally.Sponge City construction appears to be not well accustomed.The reason on for this is that China’s sponge city is still exploring the Eastern practice under the western low-impact development(LID)theory and technology,and it cannot fully cover China’s complicated national conditions.On the other hand,China continues the thousands of years of Chinese civilization,a series of ecological wisdom combined with production and life formed in th e exploration of the ancestors,and the development of urbanization.Today,water space in traditional villages have become the spatial carrier of these ecological wisdom,and how to proceed from a quantitative point of view research on the ecological wisdom of traditional villages and the extraction of ecological wisdom have become the focus of the villages research.Therefore,using Western scientific tools to describe the performance of the traditional ecological wisdom quantitatively in the East is of great significance for providing the theoretical basis and evaluation reference for the construction of China’s sponge city from the perspective of cultural self-confidence.This paper takes the Yujia Traditional Village in the Taihang Mountains Chain as the research object,and explores a performance method based on the environmental,social,and economic benefits from the perspective of the concept of landscape performance series(LPS).Based on the comprehensive analysis of the three aspects of performance,the quantitative approach and performance indicators of ecological wisdom in water space of Yujia Ancient Village were explored.First,using the ecological,social,and economic model of the Landscape Performance Series(LPS)as a prototype,with reference to comparative planning,architecture,and agricultural methods,the landscape performance model was transformed into a performance model that is applicable to quantitative research of ecological wisdom in water space of Yujia Village.Secondly,through analysis and calculation of the land layout and ecological adaptation of the study area through the "Multilayer-Cake" model based on Ian Mc Harg’s ecological wisdom,corresponding ecological performance values are obtained;and the ecological wisdom culture is communicated based on the semantic analysis of Web big data.Social performance is calculated by the TF-IDF word frequency analysis to obtain the corresponding social performance value;based on the ecological performance and social performance,combined with the relevant economic conversion data,the economic performance value is converted.Finally,combined with the results of comprehensive performance analysis of water space,we tried to put forward quantitative indicators and promotion strategies for the water-based ecological wisdom performance in Yujia Traditional Village.The research uses Landscape Performance series(LPS)as an entry point to construct an ecological wisdom performance analysis research method.The water space in Yujia Village is the representative research object,providing a quantitative assessment performance standard for ecological wisdom,and providing ecological wisdom in the practice of planning architecture.The reference of indicators provides new research ideas and practical thinking for the study of sponge cities,providing indicators for the construction of new socialist rural villages and featured towns.
