鸿恩寺公园景观林规划区生态适宜性分析

Ecological Suitability Analyses of Landscape Forest in Hongensi Park

为了探讨山地公园景观生态林规划区的生态适宜性评价机制,对重庆鸿恩寺公园的地形地貌、土壤、植被进行调查。采用因子加权叠加法对研究区域进行生态适宜性分析,确定山地公园景观生态林营造的适宜度等级。结果表明,重庆鸿恩寺公园景观生态林保护、营造生态适宜性评价值（SL）等级划分为理想（5.80~7.15）、较好（4.90~5.80）、一般（4.05~4.90）、较差（2.45~4.05）4个等级;具体的影响因子排序为坡度〉覆盖度〉土壤有机质〉高程〉郁闭度〉土壤类型〉坡向〉土壤厚度〉土壤p H。研究结果可为重庆鸿恩寺公园景观林规划决策提供相应的依据。

In order to exploring the mechanism for assessing the ecological suitability of landscape ecological forest schedule in mountainous park, an investigation on the geography, soil and vegetation cover of Hongensi park in Chongqing was carried out. The ecological suitability of research area was analyzed by the comprehensive evaluation of factors, and finally an classi- fication for the fitness of landscape ecological forest planning in mountain park was given. The results suggested that, land- scape ecological forest protection,construction of ecological suitability evaluation value of Hongensi park were divided into four ranks： ideal（5.80-7.15）,fine（4.90-5.80）,normal（4.05-4.90） and poor（2.45-4.05）;and the ranking of relevant factors was as follows： slope〉coverage〉soil organic matter〉height〉canopy density〉soil type〉aspect〉soil thickness〉soil pH value. The re- search results could provide some basis for the landscape planning of Hongensi park.
