基于低碳理念的鄂州市城市土地集约利用评价

结合国内外低碳土地利用的研究背景和实践,分析出不同土地利用方式碳排放效应,并对城市土地低碳化与集约化利用进行定性与定量分析,并采用鄂州市实际构建低碳理念下城市土地集约利用评价指标体系,对鄂州市2000-2013年土地利用状况进行分析评价.由此,总结鄂州市再加入低碳因素后土地集约利用的变化规律,并提出相关建议.     

Synopsis of ‘onychocellid’ cheilostome bryozoan genera

Genera assigned to the cheilostome bryozoan family Onychocellidae are revised based on the skeletal morphology of the type species and, when possible, the type material of these species. All genera are illustrated using scanning electron micrographs, some for the first time. Onychocellidae, which ranges from the Cenomanian stage of the Cretaceous to the Recent, has been a particularly troublesome family because of poorly defined generic concepts correlating at least in part with a paucity of morphological characters. Thirty-five genera are described in this review. Of these, two are recognised as subjective synonyms of other onychocellid genera (Rhebasia and Semieschara), one cannot be sufficiently characterised from the type material (Collura), and two are new: Aechmellina gen. nov. (type species Aechmella falcifera) and Kamilocella gen. nov. (type species Eschara latilabris). A neotype is chosen for Rhagasostoma hexagonum, the type species of Rhagasostoma. A key is provided to assist in the identification of onychocellid genera. Phylogenetic relationships between genera remain obscure and are unlikely to be fully resolved based on skeletal morphology alone. The family as an entity is loosely circumscribed and almost certainly paraphyletic, containing stem genera of other anascan familes such as Lunulitidae, Coscinopleuridae and Aspidostomatidae.
