采石类矿坑花园景观评价和模型建构
Landscape Evaluation and Model Construction of Quarry Garden

采石类矿坑花园景观评价体系是采石类矿坑花园设计优化的基础,也是揭示采石类矿坑花园内部各元素配置的合理性与科学性的依据。首先采用文献分析、观察调查、问卷调查、归纳比较等方法,对采石类矿坑花园景观的形态特征进行描述与分析;其次依据矿坑花园的景观构成要素和功能价值选取合理指标,构建采石类矿坑的景观评价指标体系;基于实地、问卷调查的数据,借助软件分析,计算各指标的权重,确定各个指标及评价总目标的取值,构建评价模型;根据科学性、实践性原则,选取3个有代表性的采石类矿坑花园,根据评价模型分析数据,对其进行景观质量评价,得出评价对象中质量等级为Ⅰ级的有1个、Ⅱ级1个,Ⅲ级有1个,进而从场地与设施舒适性、功能性、观赏性等方面,对所评价的采石类矿坑花园提出优化建议。
The landscape evaluation system is the foundation of the quarry garden design optimization,which is the rationality and scientific basis to reveal the internal elements configuration of the quarry garden and is the key point to find the intrinsic mechanism of the problem.Firstly,this paper describes and analyzes the morphological characters of the quarry garden landscape.In the next place,based on landscape elements as well as functional values,selects appropriate indicators to build a landscape evaluation system of stone pits.Based on field survey data,questionnaire survey results,and software analysis,by calculating each index,it chooses the appropriate indexes and evaluate the overall goal,and then builds an evaluation model.Pursuant to scientific and practical principles,3 representative quarry gardens are selected.According to the evaluation model,it executes data analysis and gives landscape quality assessment of the chosen gardens,comes to the conclusion that there are 1 gradeⅠgarden,1 gradeⅡones,1 grade Ⅲ ones.The last part of the paper,from the perspectives of facility-comfort,functionality,and ornament,comes up with several optimization recommendations.
