Journal ArticleDOI
Grassland degradation in China: Methods of monitoring, management and restoration
TL;DR: In this article, the authors present a review of the present situation of grassland desertification in China, and discuss mechanisms of grass land degradation, including overgrazing, cropland misuse and unregulated collection of fuel and medical plants.
Journal ArticleDOI
Quantifying grazing intensities using geographic information systems and satellite remote sensing in the Xilingol steppe region, Inner Mongolia, China
Kensuke Kawamura,Tsuyoshi Akiyama,Hiro-omi Yokota,Michio Tsutsumi,Taisuke Yasuda,Osamu Watanabe,Shiping Wang +6 more
TL;DR: In this article, a methodology was developed for quantifying the effects of grazing intensities using the normalized difference vegetation index (NDVI) obtained by the moderate resolution imaging spectroradiometer (MODIS) on-board the earth observing system (EOS) terra satellite.
Journal ArticleDOI
Seasonal visible, near-infrared and mid-infrared spectra of rice canopies in relation to LAI and above-ground dry phytomass
TL;DR: In this article, the relationship between radiometric data an and the leaf area index (LAI) and above-ground dry phytomass (GDM) was investigated during 11 development periods of 10-day intervals.
Journal ArticleDOI
Comparing MODIS vegetation indices with AVHRR NDVI for monitoring the forage quantity and quality in Inner Mongolia grassland, China
Kensuke Kawamura,Tsuyoshi Akiyama,Hiro-omi Yokota,Michio Tsutsumi,Taisuke Yasuda,Osamu Watanabe,Shiping Wang +6 more
TL;DR: In this paper, the spectral vegetation indices (VI) of Advanced Very High Resolution Radiometer (AVHRR) and Moderate Resolution Imaging Spectroradiometer (MODIS) sensors were compared with a 10-day maximum value composite from April 1 to October 31, 2002.
Journal ArticleDOI
Biometric based estimates of net primary production (NPP) in a cool-temperate deciduous forest stand beneath a flux tower
Toshiyuki Ohtsuka,Tsuyoshi Akiyama,Hashimoto Yasushi,Motoko Inatomi,Toru Sakai,Shugang Jia,Wenhong Mo,Satoshi Tsuda,Hiroshi Koizumi +8 more
TL;DR: In this paper, the authors measured the forest biomass and biometrically derived net primary production (NPP) in a deciduous forest stand under a flux tower, and compared the practicality of continuous measurement of NPP to compare with corresponding estimates of eddy-covariance based net ecosystem exchange (NEE).
