基于遥感指数的嶂石岩省级自然保护区保护成效研究摘要本研究立足于研究保护区建立所产生的综合效益和保护成效，为保护区的未来规划提供合理建议，促进保护区的全面协调发展。本文选取河北嶂石岩省级自然保护区1995年、2005年和2017年遥感影像数据，首先介绍自然保护区概况，了解研究区的地理位置及气候条件等；其次，利用遥感信息提取的方法对研究区的地表覆盖类型、植被指数(NDVI)、和水体指数(NDWI)进行分析处理；最后通过对比分析研究区的变化结果，明白建立保护区的保护成效以及提出进一步提高保护成效的对策。研究结果显示：在保护区建立后，地表覆被变化向良性转化，建筑、农田和裸地向森林植被过渡，保护区西部和西南部植被指数和水体指数明显增强，保护区保护成效效果显著。关键词：嶂石岩保护区；遥感指数；保护成效分析及对策；生态环境PAGE\*MERGEFORMATIIIABSTRACTThisstudyisbasedonthestudyofthecomprehensivebenefitsandprotectioneffectsofprotectedareas,toprovidereasonablerecommendationsforthefutureplanningofprotectedareas,topromotethecomprehensivecoordinateddevelopmentofprotectedareas.Inthispaper,theremotesensingimagedataofZhangshiyanprovincialnaturereserveinHebeiProvincein1995,2005and2017areselected,thelandcovertype,vegetationindex(NDVI)andwaterbodyindex(NDWI)ofthestudyareawereanalyzedbyusingthemethodofremotesensinginformationextraction,understandtheprotectioneffectivenessofestablishingprotectedareasandputforwardcountermeasurestofurtherimprovetheprotectioneffectiveness.Theresultsshowedthataftertheestablishmentofthereserve,thechangeoflandcoverchangedtobenign,thearchitecture,farmlandandbarelandchangedtoforestvegetation,andthevegetationindexandwaterbodyindexintheWestandsouthwestofthereserveincreasedobviously,theprotectioneffectoftheprotectedareaisremarkable.Keywords：Zhangshiyanreserve；RemoteSensingIndex；Analysisofprotectioneffectandcountermeasures；EcologicalEnvironment目PAGE\*MERGEFORMATIII录前言.......................................................................1第1章概述..................................................................21.1研究背景.............................................................21.2研究目的及意义.......................................................21.3研究内容.............................................................2第2章数据源与研究方法......................................................42.1研究区概述...........................................................42.2数据来源.............................................................52.3研究方法.............................................................6第3章结果分析..............................................................73.1地表覆被类型转变分析.................................................73.2植被指数变化分析....................................................113.3水体指数变化分析....................................................12第4章保护成效分析.........................................................144.1保护状态方面成效....................................................144.2保护压力方面成效....................................................144.3保护应对措施方面成效................................................14第5章提高保护成效的对策...................................................155.1逐步完善保护区规章制度..............................................155.2加强宣传教育........................................................155.3协调保护与经济发展的关系............................................15结论.......
