Patterns of development in tourist accommodation enterprises on farms in England and Wales

The spatial distribution of UK farm-based tourist accommodation is not known in detail, although this type of facility has been an important element in the growth of rural tourism and the most common option for farm diversification. A database of farms in England and Wales offering tourist accommodation has been prepared and the individual entries georeferenced to enable their locations to be determined with respect to selected Scenic Areas (Areas of Outstanding Natural Beauty, Heritage Coasts and National Parks). Exploratory analysis of this database indicates a possible ‘neighbourhood effect’ in which the provision of farm-based accommodation within buffer zones immediately surrounding these designated areas has a higher level of penetration in the farming community than in more distant areas. Further research is outlined to examine the interaction between actors in farming and planning communities using the geographical framework presented here.

Distribution of clay minerals in surface sediments from the eastern Barents and south-western Kara seas

Surface samples from the eastern Barents and south-western Kara seas have been analysed for clay mineralogy. Transport paths, the role of regional sources and local bedrock outcrops and the influence of hydrodynamic and glacigenous processes for clay distribution on the shelves are discussed in relation to central Arctic Ocean deep sea and sea ice sediments. Franz Josef Land and Novaya Zemlya show significantly different clay mineral associations. Although smectite concentrations are fairly high, Franz Josef Land can be excluded as a source for central Arctic sea ice sediments, which are relatively rich in smectite. In the Kara Sea, smectite concentrations in coastal sediments surpass even the Franz Josef Land concentrations. The large cyclonic gyre in the eastern Barents Sea between Novaya Zemlya and Franz Josef Land, which serves as a mixing zone between Arctic and North Atlantic water, is apparently reflected within the smectite distribution pattern. With the exception of Franz Josef Land, the area of investigation is typically low in kaolinite. In particular, coastal areas and areas north of Novaya Zemlya, influenced by the inflow of Arctic waters, show the lowest kaolinite concentrations. A high kaolinite occurrence within the Nansen Basin is most probably related to Franz Josef Land and emphasizes the importance of long-range downslope transport of sediments across the continental slope. The surface water circulation pattern in close interaction with local outcrops onshore Novaya Zemlya and locally restricted occurrences within the eastern Barents Sea significantly alter the illite dispersal pattern. Illite concentrations are lowest around Franz Josef Land. Chlorite is generally low in the area of investigation. Submarine outcrops and important chlorite occurrences onshore Novaya Zemlya bias its distribution pattern.     

辽宁省东部山区泥石流形成因素的探讨

从辽宁省东部山区泥石流暴发的特点看，暴雨只是泥石流发生的一个激发因素。泥石流活动区分布于地壳快速上升，地震活动频繁的地带，泥石流活动的高潮与该区地震活动期基本一致，由此说明辽宁东部山区泥石流其孕育、发展和活动主要受内力地质作用所控制．     

基于新视角的震害分析——以四川长宁6.0级地震为例

四川长宁6.0级地震发生后，作者第一时间前往地震现场，获得第一手震害资料。基于“散、脆、偏、单”评估法，对当地建筑物震害特点和成灾机理进行深入剖析，并提出整治措施。实际震害显示，当前我国城乡建筑亟待解决的问题是“散”和“脆”；学校建筑和底商结构在此次地震中仍表现出诸多抗震不利问题，集中体现在因填充墙布置不合理导致的“偏”；高层建筑主体结构虽在地震后保存完好，但填充墙破坏较重，修缮费用较高。震害调查结果警醒行业人员需围绕实际震害特点精准发力，优化结构概念设计，全面提升抗震能力，推动韧性城乡建设。     

滇西地震重点监视防御区中强地震潜在震源区的综合图像识别

本文利用滇西地区近些年来的地震地质、地球物理及地壳形变等方面的资料，经深入研究分析，最终选定了１２个较理想的特征参数，通过综合图像识别，在６４个研究对象中得到了２８个Ｄ类对象，占研究区总面积的４３％。其中有１６个对象历史上已有６级以上地震的记载；１２个为新判定的中强地震潜在震源区；１个为判定不稳定对象。最后给出了云南滇西地震重点监视防御区中强地震潜在震源区预测图。     

西部山区总辐射气候学计算及分布

根据西部山区太阳总辐射的实测资料分析，指出，西部山区总辐射的气候学计算必须考虑日照，水汽分布及海拔高度的影响。为此研制了适宜于西部山区的总辐射气候学计算公式Ｑ＝Ｑ０（ａ＋ｂｓ１＋ｃｓ１＾２），进而讨论了西部山区总辐射的时，空分布。     

毛毛山断裂带断层岩的特征及其意义

对毛毛山断裂带断层岩进行了宏观及微观的观察和分析，特别是对断层岩中石英颗粒的形貌特征、溶蚀类型及断层岩的组分进行了研究。结果表明该断裂是一条具有多期活动的全新世活动断裂．滑动性质以粘滑为主，断裂的东段较西段更为明显。     

滇东北山地气候特征

滇东北地势南高北低，大致以境内五莲峰和乌蒙山余脉北侧海拔≥２５００ｍ的山系为界：北部倾向四川盆地，南部属云贵高原主体。区内气候特征：１．在垂直分异上，年均温直减率０．４５－０．７７℃／ｈｍ，海拔３４０－２４００ｍ处年降水量垂直递增率２０－５０ｍｍ／ｈｍ；２．在地域分异上，南部比北部的年均温高５．０℃，年均温纬减率高０．６９℃／°Ｎ，年降水量低５４．２ｍｍ。
