Design of space-aerial-ground remote sensing monitoring system and platform for vegetation ecology in Qinling Mountains
[Purpose]As a key ecological barrier area,vegetation is an important component of the treasure house of biodiversity in the Qinling Mountains of Shaanxi province,and it has the ability of water conservation,soil conservation,wind prevention,sand fixation and carbon fixation,possessing significant ecological and economic value.Therefore,it is necessary to conduct ecological monitoring and evaluation of regional vegetation using remote sensing technology.[Method]In order to build an effective vegetation ecological remote sensing monitoring platform suitable for the Qinling Mountains region,we investigated the status and limitations of vegetation ecological monitoring technology.Then,addressing the key requirements for ecological monitoring of vegetation in the Qinling Mountains region,a conceptual framework for the construction of an integrated big data monitoring system and platform for vegetation ecology in the Qinling Mountains was established.This included three core function design ideas:space-air-ground accurate monitoring,ecological assessment,and thematic decision analysis.[Result]In summary,main monitoring indicators were screened and optimized by identifying vegetation ecological monitoring targets,and supporting monitoring methods were provided.The construction method of the space-air-ground remote sensing monitoring system for vegetation in the Qinling Mountains was preliminarily established by"establishing monitoring targets-constructing monitoring system-determining optimal system",and the evaluation scheme was determined by"cluster analysis-local modeling".[Conclusion]This study will provide a new perspective scheme for the future construction of an integrated monitoring platform with remote sensing"eye",big data"body",cloud platform"hand",and intelligent"soul"as the core.
