景观美景度评价的多尺度响应机制与系统集成

Effective protection and reasonable utilization of landscape resources has been rose to national strategy according to the aesthetic values. But the scientific and reasonable evaluation system has not been established. How to establish a systemic evaluation system is the main research objective based on the cross-scale relationship among different spatial-temporal dimension by integration with the subject and object aspects of landscape. .Several sites have been choose to explore the landscape aesthetic relationships between subjects and objects, between spectacular view and environmental background, between natural environment and humanistic spirit. We choose Wulingyuan,Lushan, Huangshan which they are most famous scenic areas in China as the case studies to have a comparative study. .Project goals are to:(1) explore the relationship between landscape elements and scenic beauty based on Chinese traditional cultural background based on several different landscape visual value assessment methods;(2)study the scaling effects of different time and spatial dimension on the cross-relationship between landscape visual quality and landscape spatial pattern;(3)construct multi-scale landscape scenic beauty evaluation model to estimate the overall landscape scenery value in three cases;(4)assess the application prospect in different kinds of landscapes. .We develop an integrated study method to explore the dynamic interactions and associated feedback among social and ecological process. Ecological data on forest landscape structure and composition come from field measurements, time-series classifications of remotely sensed images, and national forest investigation map. The social data on landscape visual quality come from visual assessment experiment and archival data..The results of this study might be useful in landscape management in cooperation with the strategy of “Beauty China”. And it is also a research attempt of geographical system science paradigm that is research frontier following two paradigms including geographical empirical paradigm and geographical positivist paradigm on landscape aesthetic assessment.

景观美学价值的有效保护和可持续利用已经上升到国家战略层面，但科学、系统地景观美学评价体系尚未建立。如何从景观主体和景观客体整体出发，重点识别景观美学评价的多尺度响应的内在机制，建立景观美景度评价系统集成模型的理论和方法是当前景观美学评价研究的核心科学问题。本项目选择武陵源、庐山和黄山等著名的风景旅游地为例，全面考虑审美主体与审美客体，风景构景与环境本底，自然环境与人文精神，围绕“传统景观美学评价——多尺度时空变化驱动机制——景观美景度评价系统集成模式”的研究主线，揭示不同尺度景观美景度的内在转换机制，构建多尺度景观美景度系统评价模型，并探索运用于景观管理的具体实践。如何构建多尺度景观美景度系统评价模型，是景观美学研究从经验范式、实证范式到系统范式的前沿科学问题，也是“美丽中国”战略实践的基础科学问题。本项目的研究将为我国景观美学资源的保护管理与开发提供理论支撑和应用模式。

景观美学价值的有效保护和可持续利用已经上升到国家战略层面。本项目全面考虑审美主体与审美客体，风景构景与环境本底，自然环境与人文精神，围绕“传统景观美学评价——多尺度时空变化驱动机制——景观美景度评价系统集成模式”的研究主线，研究了基于游览线路的多尺度景观美景度系统集成的理论与实践，构建多尺度景观美景度系统评价模型，并探索运用于景观管理的具体实践。为风景旅游地全面客观系统的景观美景度评价提供科学依据和新的应用模式，并可为“美丽中国”的景观实践作出一定的贡献。.本项目以武陵源为案例地，建立了以4个离散分布的猕猴栖息地为源及其3个潜在区为补充的核心保护区域, 划定了多条辐射道和源间联结以改善栖息地之间的连通性, 并识别出了多个生态修复关键点。本研究对景观安全格局中缓冲区和生态廊道的识别方法进行了改进, 在武陵源风景名胜区猕猴保护中的运用也具有生物保护上的实践价值。.以庐山为案例地，将动物集合种群竞争模型引入森林演替模拟中，以庐山为研究区域选取10个优势乔木种进行了森林演替模拟。在MATLAB中分别对当前生境条件、生境破坏条件和生境恢复条件进行模拟，结合庐山森林演替动态曲线和各优势种对外界条件响应规律，总结了对不同物种续存的保护机制。
