Development Model of Ecotourism Circular Economy in Lakefront Scenic Areas——A Case Study of Luchong Scenic Area by Fuxian Lake,Yunnan Province

Strategies of "guidance to different types of areas,promotion step by step" were given to study the development model of ecotourism circular economy in different types of tourist sites.By taking Luchong Scenic Area by the Fuxian Lake,Yunnan Province for an example,the general model of ecotourism circular economy in lakefront scenic areas was summarized,it was stressed that ecological principles and "5R"(rethinking,reducing,reusing,recycling,repairing)should be followed in its construction.Characteristics of a lakefront scenic area and actual conditions of its location region should be taken into consideration,with sewage treatment and lakefront environment protection as the focus,green scenic area and green tourism community as the carrier,a development model of ecotourism circular economy was established by considering relevant elements such as clean production,green consumption,waste processing,ecological compensation and industrial coupling,effective measures were given to introduce theories into practices,which would be the only chance for the lakefront scenic area realizing its sustainable development.

滨湖旅游区生态旅游循环经济发展模式探析——基于云南省抚仙湖禄充景区的个案研究

指出生态旅游循环经济应该采取"分类指导、逐步推进"的战略来研究各类景区的生态旅游循环经济发展模式。以云南省抚仙湖禄充景区为例,在对澄江旅游度假区禄充景区进行个案研究的基础上,总结了滨湖景区生态旅游循环经济发展的一般模式,强调滨湖景区生态旅游循环经济发展模式的构建应该坚持生态学的基本原理,以及再思考、减量化、再利用、再循环、再修复的"5R"原理,根据滨湖景区自身的特点和所处区域产业结构的实际,以污水处理和湖滨环境保护为中心,以绿色景区和绿色旅游社区建设为载体,考虑清洁生产、绿色消费、废弃物处理、生态补偿、产业耦合等相关要素,构建生态旅游循环经济模式,并采取切实措施,使之从理论走向实践,将是保证滨湖景区可持续发展的唯一选择。

基于多尺度NDVI的抚仙湖禄充景区植被覆盖研究

植被覆盖度是反映植物生长状况的重要参数,针对景区人类活动对植被覆盖变化的影响,论文以多个时期影像的归一化植被指数(NDVI),进行RGB合成,运用像元二分模型定量估算了抚仙湖禄充景区1996年-2016年植被覆盖度及其变化趋势,分析了抚仙湖禄充景区植被覆盖度变化,旨在为景区生态环境监测评价及管理提供科学依据。研究结果表明,禄充地区近20年来植被NDVI空间分布差异显著,植被覆盖面积与景区改建工作的波动趋势基本一致,进一步验证了利用多尺度NDVI监测植被覆盖度变化的可行性。

抚仙湖禄充风景区植被覆盖变化研究

利用遥感(remote sensing,RS)/GIS技术,分别提取2000年Landset 7 ETM、2008年Landsat5 TM和2016年Landsat 8 OLI三期影像的植被指数(NDVI值),且进行RGB合成,并利用像元二分模型估算不同时期的植被覆盖度,分析了抚仙湖禄充风景区2000~2016年间的植被覆盖变化情况。结果表明,在2000~2008年间极低(0~15%)、低(15~30%)、中高(50~70%)植被覆盖度所占面积增加,而中(30~50%)、高(70~100%)植被覆盖面积减少;2008~2016年间极低植被覆盖度所占面积增加显著,具体增加了18.991 1%,其他各等级植被覆盖度所占面积都在减少。
