| 1 | Spectral vegetation indices as the indicator of canopy photosynthetic productivity in a deciduous broadleaf forest显示文摘Aims Understanding of the ecophysiological dynamics of forest canopy photosynthesis and its spatial and temporal scaling is crucial for revealing ecological response to climate change.Combined observations and analyses of plant ecophysiology and optical remote sensing would enable us to achieve these studies.In order to examine the utility of spectral vegetation indices(VIs)for assessing ecosystem-level photosynthesis,we investigated the relationships between canopy-scale photosynthetic productivity and canopy spectral reflectance over seasons for 5 years in a cool,temperate deciduous broadleaf forest at‘Takayama’super site in central Japan.Methods Daily photosynthetic capacity was assessed by in situ canopy leaf area index(LAI),(LAI×Vcmax[single-leaf photosynthetic capacity]),and the daily maximum rate of gross primary production(GPPmax)was estimated by an ecosystem carbon cycle model.We examined five VIs:normalized difference vegetation index(NDVI),enhanced vegetation index(EVI),green–red vegetation index(GRVI),chlorophyll index(CI)and canopy chlorophyll index(CCI),which were obtained by the in situ measurements of canopy spectral reflectance.Important Findings Our in situ observation of leaf and canopy characteristics,which were analyzed by an ecosystem carbon cycling model,revealed that their phenological changes are responsible for seasonal and interannual variations in canopy photosynthesis.Significant correlations were found between the five VIs and canopy photosynthetic capacity over the seasons and years;four of the VIs showed hysteresis-type relationships and only CCI showed rather linear relationship.Among the VIs examined,we applied EVI–GPPmax relationship to EVI data obtained by Moderate Resolution Imaging Spectroradiometer to estimate the temporal and spatial variation in GPPmax over central Japan.Our findings would improve the accuracy of satellite-based estimate of forest photosynthetic productivity in fine spatial and temporal resolutions,which are necessary for detecting any response of terrestrial ecosystem to meteorological fluctuations. | Hiroyuki Muraoka Hibiki M.Noda Shin Nagai Takeshi Motohka Taku M.Saitoh Kenlo N.Nasahara Nobuko Saigusa | 2013 | Journal of Plant Ecology2013，6，5： | 8 |
| 2 | A pilot randomized control study to evaluate endoscopic resection using a ligation device for rectal carcinoid tumors显示文摘瞄准:比 10 公里小的直肠的良性肿瘤肿瘤能是有用内视镜检查法的本地切除的 resected。以便完全移开直肠的良性肿瘤肿瘤,我们在这飞行员控制与一台结扎设备评估了内视镜的粘膜切除术使随机化的学习。方法:十五个病人从 1993 ~ 2002 在我们的医院里与直肠的良性肿瘤肿瘤(不到 10 公里) 被诊断。有 9 男性和 6 女性,与吝啬的年龄 61.5 年(范围, 34-77 年) 。病人没有良性肿瘤症候群症状的抱怨。十五个病人随机被划分成 2 个组:7 个良性肿瘤肿瘤被常规内视镜的切除术治疗,并且 8 个良性肿瘤肿瘤被内视镜的切除术用一台结扎设备治疗。结果:所有直肠的良性肿瘤肿瘤在中间被定位到远侧的直肠。从 3 公里改变到 10 公里和病人的背景特征的肿瘤的尺寸不在二个组是不同的。用一台结扎设备的良性肿瘤肿瘤的完全的移动的率(100% , 8/8 ) 比常规内视镜的切除术的显著地高(57.1% , 4/7 ) 。三个病人有深边缘,另外的治疗为被执行的肿瘤参与。没有复杂并发症用一台结扎设备发生了在期间或在内视镜的切除术以后。在两个组的所有病人在 3 年的观察时期期间是活着的。结论:用一台结扎设备的内视镜的切除术是为小直肠的良性肿瘤肿瘤的切除术的一个有用、安全的方法。 | Hiroyuki Sakata Ryuichi Iwakiri Akifumi Ootani Seiji Tsunada Shinichi Ogata Hibiki Ootani Ryo Shimoda Kanako Yamaguchi Yasuhisa Sakata Sadahiro Amemori Kotaro Mannen Masanobu Mizuguchi Kazuma Fujimoto | 2006 | World Journal of Gastroenterology2006，12，25： | 2 |
