The Microclimate Comfort Study For Scenic Spots In Humid And Hot Area

The tourism climate comfort is the important aspect to influence the tourism activities. The tourists choose different scenic spots and different activities according to difference season. Although in same scenic spot with same season, the tourists have different recreational behaviors because of different microclimate. Some scenic spots attract tourists by regulation microclimate with mechanical equipments. This way increases the energy consumption and operation cost, and deteriorates the outdoor environment, which cannot satisfy the expectation of pleasant climate and more outdoor activities. So, it is the sustainable development way for scenic spots to plan and design natural, healthy and pleasant landscape to adapt or regulate the microclimate.Although people at home and abroad also recognize that the important significance of climate comfort for tourism development and operation, especially the microclimate of scenic spots, little research on correlation microclimate of scenic spots. This paper determinates the main study contents and obtains a little result.Firstly, it sets up the evaluation method of microclimate. According to comparative study the ways of microclimate evaluation methods at home and abroad, and according to the most tourists’activities outdoor, this paper puts forward the comprehensive evaluation indexes and grades for microclimate of scenic spots. It uses WBGT index to evaluate summer microclimate comfort and TS index for spring, autumn and winter microclimate comfort in scenic spots and it clarifies the microclimate comfort in to7grades:very cold, quite cold, cold, comfort, hot, quite hot, very hot, and each comfort value corresponds to each different grade.Secondly, basing the microclimate comfort, it studies the climatic divisions of scenic spots, and defines different climatic region, especially the hot and humid climatic region, which provides the technical basis for climatic divisions of domestic scenic spots. The way is to classifies the scenic spots in Sichuan province into3climatic regions by using WBGT index and TS index, and classifies3climatic regions into5climatic regions according to the humid and temperature furthermore. Those are dry cold region, humid cold region, and humid hot region with hot in summer and cold in winter, humid hot region with hot in summer and warmer in winter, and the warm region.Through analysis characters of5climatic regions, it finds that the humid hot region with hot in summer and cold in winter is the most complex climate, and has the most difficult way to adapt the climate. However, the quantity of the tourists is the most and the grade for the scenic spots is the highest. So, it chooses the hot humid scenic spots as research object. Thirdly, it studies the microclimate comfort threshold of tourists’activities in scenic spots, and analyzes the correlation between microclimate comfort threshold and tourists behavior, which provides the technical reference system for building comfortable micro-environment of landscape in scenic spots.According to the the environment--acts theory of Kurt Levin, it studies the relation between tourist action and microclimate comfort in hot humid scenic spot—the Tu Fu’s former residence in Chengdu. It studies the microclimate comfort threshold to suite the tourism activities basing on the need of tourists. Through measurement of microclimate parameters and notes on the recreational behaviors of tourists and the questionnaire, and it studies the relationship among them and obtains as following:in summer, the microclimate comfort threshold(WBGT value) is<30℃; in spring, autumn and winter, the microclimate comfort threshold(TS value) is>2℃.Fourthly, it studies different landscape elements, such as pavement, plant, water and architecture, to influence the microclimate comfort in seasons, which provides the theoretical basis and technical support for the microclimate suitability of landscape elements designing in scenic spots planning.Fifthly, taking Dongping village in Penzhou city as example, it studies the rural eco-tourism landscape planning and constructing oriented to improving microclimate in scenic spot of hot and cold region. The results of investigation, measurement and analysis between pre-and post of planning and construction show:it is relative one of the simple, practical and low-cost way to improve the microclimate comfort of site by using plant, water, road and architecture to planning rural ecotourism landscape. It is also the embodiment of humanism.
