滨海体育休闲海域空间适宜性评价——以厦门岛东南部滨海为例

本文以滨海体育休闲对海域空间支撑要求为出发点,以厦门岛东南部滨海为例,从资源条件、自然环境条件和社会条件等3方面,构建滨海运动休闲海域空间适宜性评价指标体系,在专家咨询的基础上采用层次分析法确定指标权重,评价滨海体育休闲海域空间适宜性,研究结果显示:(1)滨海体育休闲海域空间适宜性由南向北逐渐增强,最北部的观音山区较为适宜开展滨海体育休闲活动;(2)自然环境因素是衡量滨海体育休闲海域适宜性的首要因素;(3)决定水上滨海体育休闲海域空间适宜性的重要指标为海水浴场健康指数、海域面积、平均流速、低潮高地暗礁面积比例等,决定沙滩滨海体育休闲海域空间适宜性的重要指标为海滩平均宽度、平均坡度、清洁度等。

Sea area suitability assessment of coastal sports leisure:a case study in southeast of Xiamen Island

An evaluation index system for the sea area suitability of coastal sports leisure is established from three aspects:resource condition, natural environment condition and social condition. On the basis of expert consultation, the weight of the index is determined by analytic hierarchy process. Then the sea area spatial suitability of coastal sports leisure in southeast of Xiamen Island is assessed. The results show that the sea area spatial suitability of coastal sports leisure is gradually enhanced from south to north, and the northern area Guanyinshan is the most suitable area for coastal sports leisure activities. The identification of natural environmental conditions is the primary factor to measure the sea area suitability of coastal sports leisure. The important indicators to determine the suitability of offshore sports area include the health index of seawater bathing area, the area of coastal sports leisure, the average current velocity, area ratio of low tide and high ground reef, etc. The key indicators that determine the suitability of beach sports leisure are beach average width, average slope, cleanliness, etc.
