【摘要】：【目的】为我国山地风景区景观资源评价、利用、管理以及山地旅游经济发展提供参考。【方法】以地处我国秦巴山区的花萼山为例,基于遥感和GIS技术,利用NDVI、高程变异系数、坡度、坡向等特性进行区域性自然景观特征分析,并综合考虑山地风景区的特点,采用德尔菲法、层次分析法、模糊数学评价法进行景观资源综合评价。【结果】花萼山NDVI分布于0.50~0.72,植被丰富,覆盖率高;高程变异系数为24.59%,相对高差较小,景观视觉冲击性一般;坡度在25~38°范围内占总面积的42.62%,微地形下景观变化多样,景观效果好;阳坡占总面积16.84%,阴坡占20.45%,均处于劣势,景观优越区较少;盐茶古道、扁桶峡、大竹河、花萼主峰、长洞湖、曹家峡资源综合得分均超过7.100,综合价值最高;综合得分在6.300~7.000的资源主要分布于西南部,具有较高的现实开发价值。【建议】花萼山景观资源开发应坚持以生态为基础、与文化相结合,以圈层明梯度、以分区显层次,以交通为骨架,突出重点建设的策略。
[Abstract]:[objective] to provide a reference for the evaluation, utilization, management and economic development of mountain tourism in China. [methods] A case study of Calyx Mountain, located in Qinba Mountain, China, based on remote sensing and GIS technology, was made. Using NDVI, coefficient of variation of elevation, slope, slope direction and other characteristics to analyze the regional natural landscape characteristics, and considering the characteristics of mountain scenic area, Delphi method, analytic hierarchy process (AHP) is used. The comprehensive evaluation of landscape resources was carried out by fuzzy mathematics method. [results] the NDVI distribution of Calyx Mountain was 0.500.72, the vegetation was rich, the coverage was high, the coefficient of variation of elevation was 24.59, the relative height difference was small, and the visual impact of landscape was normal. The slope takes up 42.62 of the total area in the range of 25 掳38 掳, the landscape changes are various under the microtopography, and the landscape effect is good; the sunny slope occupies the total area of 16.84, the overcast slope occupies 20.45% of the total area, all of them are at a disadvantage and there are few favorable landscape areas; the ancient Yancha Road, the flat bucket gorge, the Dazhu River, the main peak of the calyx, and the Changdong Lake, The comprehensive score of Caojiaxia resources is above 7.100, the comprehensive value is the highest, and the resources with the comprehensive score of 6.300 ~ 7.000 are mainly distributed in the southwest, which has higher realistic value of exploitation. [suggests] the exploitation of landscape resources in Calyx Mountain should be based on ecology. Combined with culture, the strategy of focusing on construction is to take the gradients of the circle layer, the explicit level of the district and the skeleton of the traffic as the skeleton.
