Haikou City, the coastal tourist areas selected for the study, through comprehensive literature review and conduct field visits, collection area topography, hydrology, land use, traffic, vegetation, geology and other natural conditions, basic data analysis and sorting through access to yearbook regional socio-economic and Travel status information; tourism as the basis for building ecological suitability evaluation index system. In 2008 remote sensing image as the main data source, extraction of land use and vegetation status information; build slope study area, roads, place names, rivers, waters and other basic information about GIS spatial / attribute database. GIS / RS based technology, the study area single factor Tourism suitability analysis and evaluation, and filter out the limiting factor; using expert valuation method to determine the factor weights, the last comprehensive empowerment superposition analysis, re-grading (Reclassfy) obtained after Haikou Binhai eco-tourism area divided suitability 4 thematic maps. On this basis, analyzes the sea coastal tourist areas and coastal tourism belt Qiongbei relationship, and thus the regional tourism development were discussed. The results show that: 1. Region is not suitable for large-scale development of the region's widespread, accounting for 80% of the total area. Among them, \the middle of the study area north of the coastal city center, off the east coast region of southwestern less accessible lava plateau region, the other main lakes ponds scattered waters, an area of ??16,730.55 hectares, accounting for 27.34% percentage. 2. \From space, showing obvious zonal distribution characteristics, namely coastal, river, along the edge of the city distribution, tourism resources are concentrated on higher density, more reasonable mix of resources \. Three. \Zonal distribution also presents certain characteristics, but more concentrated in the west of Haikou City and study area northwest coast. In addition, the northern coast of Haikou City, a small area in the east along the Nandu distribution; eastern part of the study area, near the small area Dongzhaigang distribution. The part of the region is the city - suburban superior location, infrastructure, land use lowest cost, best ecological environment, landscape combination richest highest density of tourist resources, tourism resources, the most reasonable combination of the area belongs to priority development areas. Suitable for the construction of tourism infrastructure, hotels, tourism and real estate development. 4 of tourism ecological suitability assessment has some relative, a measure of the relative condition merits within the same region.
