摘要： 通過(guò)界定旅游型海島景觀生態(tài)健康概念，建立了以壓力狀態(tài)-響應(yīng)模型為評(píng)價(jià)模型的旅游型海島景觀生態(tài)健康評(píng)價(jià)體系，確定了理想健康狀態(tài)值。采用熵權(quán)-灰色關(guān)聯(lián)模糊評(píng)價(jià)法計(jì)算評(píng)價(jià)結(jié)果，并根據(jù)與理想值的差距程度，將評(píng)價(jià)結(jié)果劃分為5個(gè)等級(jí)。依據(jù)評(píng)價(jià)結(jié)果識(shí)別旅游型海島景觀生態(tài)系統(tǒng)具體的受損情況，及其主要脅迫因子和演化趨勢(shì)，為生態(tài)修復(fù)與優(yōu)化措施提供科學(xué)依據(jù)。以旅游型海島典型代表媽祖圣地湄洲島為案例，在RS與GIS技術(shù)支持下，整合其1993、1999、2005、2009年衛(wèi)星遙感和社會(huì)經(jīng)濟(jì)統(tǒng)計(jì)調(diào)查數(shù)據(jù)，進(jìn)行了實(shí)證研究，研究過(guò)程和結(jié)果證明了旅游型海島景觀生態(tài)健康評(píng)價(jià)體系與方法是可行的，可為資源環(huán)境管理提供依據(jù)。

Abstract: By defining the concept of landscape ecological health of tourist islands (LEHTI), a LEHTI evaluation system was established with the model of pressure-stateresponse, and an ideal health state value was determined. In addition, by adopting the methods of entropy weight and gray correlation fuzzy, the evaluation results were calculated and classified into five grades, according to their distances to the ideal value. Based on these results, the specific damage of tourist island landscape ecosystem as well as the main stress factors and the evolution trend behind the damage were identified, which could provide scientific basis for the subsequent ecological restoration and optimizing measures. Taking the representative tourist island of Mazu Holy Land as a case, and with the support of RS and GIS techniques, the satellite remote sensing and socioeconomic survey data of 1993, 1999, 2005, and 2009 were integrated and emonstrated. The process and results of this case study showed that the LEHTI evaluation system and its methods were feasible, and could provide solid basis for resource and environment management.
