Message
During Mater course, we developed grid-cell-analysis methodology in investigating spatial-temporal dynamics and driving factor of grassland degradation and has clarified that coal mining activities has become the dominated driving factor to land degradation in Inner Mongolia of China.
During Doctoral course, we used hyperspectral reflectance measurement to model the relation between land surface and remotely sensed data to monitor and investigate ecosystem degradation problem. One of her studies has improved the accuracy of large-scale monitoring of soil salinization issues in arid land .
Currently, Dr Qian has been working on using fine resolution remote sensed images to estimate the forest above ground biomass.
修士課程において、リモートセンシングとGIS技術に基づいて土地被覆や土地利用の時空間変動解析において、中国の内モンゴル自治区において、採炭活動が土地劣化の主要な推進要因になっていることを明らかにしました。
博士課程において、ハイパースペクトル設備を使用して、紫外-可視-近赤外線域で波長毎のバンド情報の分析で、リモートセンシングデータと地上生態系問題の関係をモデル化することを試みました。乾燥地における広い範囲で土壌塩類化のモニタリングの精度を改善するために重要な一環と見なされます。
現在は、国立環境研究所で特別研究員として、森林リモートセンシング技術を用いて、地域レベルの森林地上バイオマスの推定に関する研究に取り組んでいます。
