Spatial-temporal Characteristics of Land Use Intensity of Coastal Zone in China During 2000–2010

Based on remote sensing and GIS techniques, land use maps in 2000, 2005 and 2010 in China′s coastal zone were produced, and structural raster data of land use were further generated to calculate land use intensity comprehensive index(LUICI) for analyzing land use spatial-temporal characteristics at 1 km scale. Results show that: 1) from the perspective of spatial patterns of landforms at a macro scale, there is a significant difference in land use intensity between the north and the south of China′s coastal zone. Hotspots of changes mainly concentrated in metropolitan areas, estuaries and coastal wetlands; 2) elevation is an important factor that controlling land use spatial patterns at local scale. Land use intensity is much higher within areas below the elevation of 400 m and it decreased significantly as the elevation increasing; 3) there is a significant land-ocean gradient for land use intensity, which is low in island and near-shore areas, but high in the regions that 4–30 km far away the coastline because of much intensive human activities; however, in recent decades land use intensity had been promoted significantly in low near-shore area due to extensive sea reclamations; 4) significant differences of land use intensity were also found among provincial administrative units. A rising trend of land use intensity was found in provincial-level administrative units from 2000 to 2010. To sum up, elevation, land-ocean gradient, socio-economic status and policy are all influencing factors to the spatial patterns and temporal variations of land use intensity in China′s coastal zone.

恢刺经筋结点治疗中风后下肢痉挛性瘫的临床观察

目的:观察恢刺经筋结点结合头针、电针治疗中风后下肢痉挛性瘫的临床疗效。方法:根据随机抽样法,将40例中风后下肢痉挛性瘫的患者分成治疗组和对照组。其中治疗组、对照组各20例,分别采用恢刺法结合头针、电针治疗和传统针刺法治疗。结果:治疗组和对照组差异有显著性意义。结论:恢刺经筋结点结合头针、电针治疗中风后下肢痉挛性瘫的疗效优于传统针刺组。
