Under the current government strategy of building a Silk Road economic belt, tourism in Chinese border counties has becoming increasingly popular. Studying tourism competitiveness in Chinese border counties is of sizable theoretical and practical importance, as there are several notable factors involved. In this study, we constructed a tourism competitiveness evaluation model based on eight factors: natural environment, tourism resource, location and transportation, social environment, tourism service facility, border port, tourism industrial cluster and tourism market. We then analyzed the spatial characteristics of tourism competitiveness in border counties and identified five types of border counties: resource advantage type(RA), border-port advantage type(PA), location advantage type(LA), agglomeration advantage type(AA), and relative balance type(RB), and examined the correlation between tourism market competitiveness and interior competitiveness factors in the counties from 2006 to 2011. Results showed that tourism resource, location and transportation, and tourism service facility are the most important competition factors for RA border counties during the study period. Competition factors in PA counties transferred from tourism resource, social environment and tourism service facility to border port and tourism industrial cluster; competition factors in LA counties transferred from natural environment and tourism resource to tourism service facility and tourism industrial cluster and border port. Competition factors in AA counties transferred from tourism service facility to tourism resource. Tourism industrial cluster, tourism service facility and tourism resource proved to be important competition factors in RB counties. The findings of this study can be used to target tourism strategies according to different county types.

Due to the complex dynamic of aeolian and fluvial interacted processes behind the landform development,most of previous works started from classifying the types of landscape characterized by various aeolian and fluvial *** classifications are usually generalized based on large geomorphic data set abstracted from satellite images without field verification and dynamic field *** this study,we identified river banks in deserts as a unique geographical unit dominated by aeolian-fluvial *** distinct locations have been identified as representative study cases,which are in the Keriya River Basin in the west,the Mu Bulag River Basin in the middle and the Xar Moron River Basin in the east of the northern *** aeolian-fluvial interaction types were quantified based on site observation and measurement,topographic mapping and remote-sensing image *** morphological relationship between river channel and adjacent sand dunes areas were *** concluded that different channels are often associated with different distributions of riparian *** quantitative data enabled us to distinguish statistically four different types of landscape in aeolian-fluvial dominant environment,namely riverside dunes-straight channel,symmetrical interleaving dunes-meandering channel,river-island dunes-braiding channel,and grid-like dunes-anastomosing channel,aiming to provide compensational information to current aeolian-fluvial interaction *** angle of interaction between aeolian and fluvial systems,the windward and leeward sites of the bank,vegetation coverage and underlying landform determines the distribution,morphology,scale and direction of extension of the riparian *** results of the work study can provide a reference for study of aeolian-fluvial interactions at different spatial scales in arid region.

Tight sandstone gas serves as an important unconventional hydrocarbon resource, and outstanding results have been obtained through its discovery both in China and abroad given its great resource potential. However, heated debates and gaps still remain regarding classification standards of tight sandstone gas, and critical controlling factors, accumulation mechanisms, and devel- opment modes of tight sandstone reservoirs are not deter- mined. Tight sandstone gas reservoirs in China are generally characterized by tight strata, widespread distri- bution areas, coal strata supplying gas, complex gas-water relations, and abnormally low gas reservoir pressure. Water and gas reversal patterns have been detected via glass tube and quartz sand modeling, and the presence of critical geological conditions without buoyancy-driven mecha- nisms can thus be assumed. According to the timing of gas charging and reservoir tightening phases, the following three tight sandstone gas reservoir types have been identified：（a）＂accumulation-densification＂（AD）, or the conventional tight type, （b）＂densification-accumulation＂（DA）, or the deep tight type, and （c） the composite tight type. For the AD type, gas charging occurs prior to reser- voir densification, accumulating in higher positions under buoyancy-controlled mechanisms with critical controlling factors such as source kitchens （S）, regional overlaying cap rocks （C）, gas reservoirs, （D） and low fluid potential areas （P）. For the DA type, reservoir densification prior to the gas charging period （GCP） leads to accumulation in depres- sions and slopes largely due to hydrocarbon expansive forces without buoyancy, and critical controlling factors are effective source rocks （S）, widely distributed reservoirs （D）, stable tectonic settings （W） and universal densification of reservoirs （L）. The composite type includes features of the AD type and DA type, and before and after reservoir densification period （RDP）, gas charging and accumulation

本文基于可持续发展理论视角，以西南民族地区为例，构建涵盖“经济—社会—自然”3个层面的衡量规模性返贫风险因素的评价指标体系，运用综合度量模型、贡献度模型以及最小方差模型，对规模性返贫风险程度、因素和类型进行分析。结果表明：一是规模性返贫风险程度分布呈现“两头小中间大”的橄榄型态势，表明西南民族地区脱贫后仍存在不稳定因素。二是基于贡献度模型计算结果，西南民族地区规模性返贫风险因素的次序为产业因素＞能力因素＞经济因素＞政策因素＞自然因素＞文化因素＞家庭因素。三是根据最小方差模型，规模性返贫风险类型可划分为单风险、双风险、三风险、四风险、五风险、六风险和七风险返贫型7种，但西南民族地区的七风险返贫型最接近于理论模型，表明其规模性返贫风险由多种因素综合构成。基于此，研究提出建立产业防线、重视能力提升、筑牢经济基础、优化政策体系、明确返贫风险、建设反贫文化、强化帮扶职责七点防止规模性返贫的政策启示。
