| In western cities of China, mountainous parks built by relaying on natural mountain terrain can be found everywhere and they are beautiful scenery of cities due to their stereoscopic topography, the strata of landscape and their fusion with cities. Meanwhile, they are organic components of urban overall landscape image. However, only a few people conducted systemic research on plan of plant landscape of mountainous parks and ignored their value in urban landscape. In order to promote development of urban landscape construction, it is an urgent task to provide theoretical research support for plant landscape of mountainous park at the level of plan on the urban landscape visual analysis. With plant patch of plants landscape of mountainous parks as research object, this paper studied following aspects of overall plants landscape planning in external appreciation of parks from the perspective of urban landscape.(1) Via field survey on overall plants landscape of mountainous parks in Chongqing, this paper took plants landscape of mountainous parks in top-ridge park, slope park and valley park in spring and summer outside as the basic materials of evaluation and research and combined it with existing theoretical research on plants landscape pattern of mountainous parks to summarize and analyze current situation and problems of overall plants landscape of mountainous parks from the topography, vegetation status and relationship with urban landscape these three aspects.(2) With beauty value evaluation method, it worked out aesthetic evaluation on photos of materials on current overall plants landscape of mountain parks of Chongqing and combined it with SD semantic analysis and diversified linear regression analysis to screen influencing factors to beauty value of these parks and rank their influencing degree: color lightness, color harmony of park landscape, vegetation significance, richness of vegetation space, integrity of park landscape, hierarchical richness of community outline, diversity of patch types, and coordination of regional landscape, based on which it shaped beauty value model of overall plants landscape of mountain parks of Chongqing: SBE=1.654+0.287X1+0.376X2—0.114X3+0.328X4+0.11X5+0.119X6+0.16X7+0.207X8X1 represents vegetation significance, X2 represents color lightness, X3 represents diversity of patch types, X4 represents color harmony of park landscape, X5 represents coordination of regional landscape, X6 represents hierarchical richness of community outline, X7 represents integrity of park landscape, X8 represents richness of vegetation space.(3) Based on evaluation result of SBE and in combination of Google-earth aerial photos with data of field survey, this paper conducted quantitative analysis on range of visibility, scale, color and outline of patch of plants landscape with good aesthetic effects in top-ridge park, slope park and valley park, and summarized characteristics of their overall plants landscape, based on which it explored the model of structuring plants landscape in such aspects as type and scale of plant patches, spatial layout, color and hierarchy of outline and provided the model to refer to for planning overall plants landscape of mountainous parks.(4) According to current problems in overall plants landscape of mountainous parks of Chongqing and guidance of related theories, this paper proposed five principles for structuring overall plants landscape of these parks, including: “ecological characteristic, people orientation, landscape, cultural feature and integrityâ€, under the guidance of which it proposed the strategies for planning overall plants landscape of mountainous parks in three aspects: park topography,surrounding buildings and surrounding roads, and provided thoughts to refer to for subsequent planning of overall plants landscape of mountainous parks. |
