Ten-years' dynamics of the normalized relative vegetation index of biomass (NDVI) in the plant cover in steppes of the northern part of central Mongolia

Today recovery of the ranchland, protection of stock-breeding business from risk and stability of economic standing of stock farmers depend on the efficient use of ranchland and regulation of the pasture load. This is why it is topical to determine the period of the pasture use of the steppe plants correctly, to identify regularities of the ranchland changing and recovery. Based on the analysis of data pf the normalized vegetation index (NDVI) for the period 2000-2010 the map of the NDVI distribution and its relative variability has been drawn up for the Northern part of Central Mongolia. By the example of the Northern part of Central Mongolia it was shown that the dominating factor affecting changes in the NDVI vegetation index is the climatic factor. Loss in the NDVI values in the steppe zone observed in the 2000-2010's and vegetation degradation most probably feature temporal cyclic nature that can be worsened due to the anthropogenic burden. Loss in the NDVI values in the steppe zone was observed in the 2000-2010's, the plant cover changes depending on the weather factors but today such changes also take place as the result of the wrong human activity. The study of distribution of the vegetation index across the Northern part of Central Mongolia and the area with the natural steppe vegetation showed the viability of the NDVI use for simulation of dynamics of the plant cover state in the agricultural regions

Digital Archive of the 17th century Mongolian Temple khiid

publisher奈良　モンゴル国では、数多くの重要な遺跡が残っているが、修復や保存がされているものは少なく、消失の危機にある遺跡もある。遺跡の現状を保存するためにデジタルアーカイブすることが急務である。本研究の目的は、これらの遺跡をデジタル化することであり、本稿では、17世紀にザナバザルによって建立された仏教寺院であるSardgiin　ｋhiidをデジタルアーカイブした方法について述べる。本研究では、３次元レーザー計測装置によるレーザ計測とドローン（小型無人飛行機）を利用した画像計測の２種類の方法を用いた。３次元レーザ計測装置は、精度の高い計測が可能であるが、広範囲を計測する場合には時間がかかる。一方で、ドローンを使って上空から遺跡を撮影し、画像計測をする場合には、３次元レーザ計測装置よりも精度は低いが、広範囲を短時間で計測することが可能である。計測した結果から、Sardgiin khiidの構造を明らかにした。さらに、構造をより明確に提示できるようにするために、3Dプリンタを利用してデジタル化したSardgiin　ｋhiidを、出力した結果について述べる
