Tourist's satisfaction degree is one of the important indexes to evaluate the service quality of scenic spot.Taking Xi'an Dongda Hot Spring Resort Area for an example,with the expectation difference theory and customers' satisfaction evaluation model as the theoretical basis of the research,the overall satisfaction degree of tourists to hot spring resort area,and the actual sensation accomplishments and the expectation difference of each service index were analyzed by using regression analysis and paired sample t test method.The results showed:① The overall satisfaction degree of tourists to the resort area was higher.There were remarkable correlation among three variables:the sensation value,the overall satisfaction degree,and the tourist's loyalty degree;② Generally,the sensation actual accomplishments of 15 service appraisal factors were higher than the expectation value.According to the characteristics,these 15 service appraisal factors were divided into 5 groups.Some unsatisfactory aspects were found out,and the corrective measures were put forward. 展开更多

Most vein minerals deposited in fractures of the Jialingjiang Formation from Libixia section, Hechan area include a large amount of saddle dolomite and accompanying celestite, calcite and fluorite. This study analyzed the nature, source, evolution of the fluids by plane-light petrography, fluid-inclusion methods, cathodoluminescence images, and stable isotopic compositions. The homogenization temperatures of two-phase aqueous fluid inclusions in dolomite range between 100 and 270℃. Combined with the jlSO data, it is suggested that the fluid responsible for the precipitation of fracture fillings have δ18O values between 10%o and 18‰ (relative to SMOW). The saddle dolomite and the accompanying minerals were the result of activity of dense brines at elevated temperatures. Moreover, analysis shows that the fluid was derived from a mixture of marine-derived brine and deeper circulating flow. This fluid was enriched in Sr during diagenesis and formed celestite in fracture and for regional mineralization. Dissolution of saddle dolomite was attributed to the cooling of Mg/Ca-decreased fluids, which may relate to a leaching of gypsum to celestite in surrounding carbonates. 展开更多

Using different color palettes, temperatures can be well-represented in the resulting image. However, most color palettes in hot tropical places like the Philippines are unsuitable since the ambient temperature is almost the same as the scanned object or person. This study evaluates twelve (12) known and used color palettes in the market to determine the most suitable for tropical places using the edge/border tracing algorithms Sobel-Feldman and Laplacian. The result shows that color palettes with the most colors produce more noise, making it difficult to distinguish the object scanned from the background. On the other hand, color palettes with three or fewer contrasting colors produce crisp and more detailed results. This study helps developers and researchers efficiently use color combinations suitable for hot weather for an effective thermal scanning and image representation. 展开更多

There are many state-level poverty-stricken counties in the dry-hot valley areas of Jinsha River in China,with a wide range of poverty and extreme degree of poverty.The industry-supporting poverty alleviation ranks first in the"five batches"of China's targeted poverty alleviation strategy.The practice of planting in Luquan County since 2017 shows that the valleys and slopes on the dry-hot valley areas of Jinsha River with an altitude above 1800 m have wide land suitable for sorghum planting,and suitable for introduction and planting.In recent years,the county has adopted the mode of enterprise+government+cooperative+poor household,introduced the Langzhitang wine factory,developed sorghum planting with large-scale,industrialized and specialized features to achieve stable income growth for the poor,and significant results have been achieved.Based on many field surveys,household surveys,and interviews with county and village leaders,this paper analyzes the specific practices and main effects of the county's poverty alleviation model by developing sorghum planting industry,aiming to provide necessary reference for the targeted poverty alleviation and poverty alleviation in similar areas of Yunnan Province and other provinces. 展开更多

The purpose of this study is to consider crime prevention measures in ethnic areas focusing on Crime Prevention through Environmental Design (CPTED) by an analysis of crime data and field survey. In this study, it was found that the main type of foreign crime that occurred in the research area was violence, and crimes committed by Koreans, which were mainly violence and crimes such as burglary, theft, robbery, and sexual offences, occurred steadily. Because it was found that crimes were related to the urban planning elements comprised of land use such as traditional market, inn, pub, and complicated space structure and the architectural design for natural surveillance and security facilities such as CCTV, lighting, alarm, and target hardening device, a new strategy for crime prevention design should include street environmental management, improvement of commercial facilities, and reinforcement security device of each buildings has to be spread through support of policy. In conclusion it was thought that CPTED would be a valuable measure to prevention crime and support community activities in ethnic area as expecting an improvement of physical environment and resident participatory for safer community. 展开更多

Urbanization in recent years plays an important role in increase in impervious areas with reducing in vegetation cover and pervious areas of natural landscape. This leads to a rise in temperature of urban areas, by several degrees particularly at night [1,2]. A novel geospatial approach has been adopted to determine the maximum temperature areas (hot spots) over Kamrup Metro District of Assam, which is a gateway for seven neighboring north eastern states of India. The G statistics have been calculated for detecting the presence of hot spot or cold spot over the entire study area which is a new approach in urban heat island studies. The resultant z-scores and p-values show the pixels with either high or low values cluster spatially. For statistically significant positive z-scores, the larger the z-score is, the more intense the clustering of high values (hot spot) and vice versa. Land Surface Temperature (LST) anomaly values and percentage of Impervious Surface Area (ISA) along with climatic data are used to conform the hot spot location. It is one of the densely populated areas with more commercial pockets thereby giving rise to anthropogenic heat discharge which accelerates the heat island phenomenon. Incorporation of socio-economic survey data as well as certain biophysical parameters can be used to know about the cause and future impact of urbanization. 展开更多

为了解云南湿热区不同柑橘品种最佳采收期,以德宏地区主栽品种为材料,于果实转色期开始分析可溶性固形物、可滴定酸含量、单果重、可食率等变化。结果表明,金秋砂糖橘8月20日即成熟可采摘,单果重、纵径、横径、可食率和可滴定酸含量基... 为了解云南湿热区不同柑橘品种最佳采收期,以德宏地区主栽品种为材料,于果实转色期开始分析可溶性固形物、可滴定酸含量、单果重、可食率等变化。结果表明,金秋砂糖橘8月20日即成熟可采摘,单果重、纵径、横径、可食率和可滴定酸含量基本稳定,可溶性固形物含量缓慢增加,成熟期最早,且保持较高品质的时间较长。冰糖橙11月下旬成熟,单果重、纵径、横径趋于稳定,果皮较薄,可食率较高,固酸比较高且稳定,1月20日后可食率、固酸比明显下降,故采收期为11月下旬至1月下旬。砂糖橘、红江橙和W.默科特于12月初开始成熟,单果重、纵径、横径趋于稳定,可食率较高,固酸比较大,砂糖橘和W.默科特1月20日后可食率大幅降低,需尽快完成采摘;红江橙3月5日之后皮厚增加,不宜再采摘。探戈和茂谷柑12月下旬开始成熟,单果重、纵径、横径趋于稳定,可食率较高,固酸比较大,探戈2月5日后固酸比下降,因此,2月5日需完成采摘;茂谷柑3月5日后可食率明显降低,不宜再采摘。沃柑2月5日可溶性固形物和固酸比较高,可开始采摘,4月5日达最大值,可结束采摘。无籽沃柑2月下旬可采摘,此时可食率高,可溶性固形物和固酸比较大,3月5日后皮厚增加,不宜再采摘。本研究为德宏地区柑橘果实成熟期果实特性及采收期的确定提供了科学依据。 展开更多

夏县热水区地处中条山山前断裂,采集该区5个地下热水井样品,测试其地球化学成分及氢氧同位素组成,获得该区域水文地球化学特征,以期深化对该区温泉地球化学成因以及断裂带地震活动性的认识,为山西南部震情跟踪、流体异常核实和地震研判... 夏县热水区地处中条山山前断裂,采集该区5个地下热水井样品,测试其地球化学成分及氢氧同位素组成,获得该区域水文地球化学特征,以期深化对该区温泉地球化学成因以及断裂带地震活动性的认识,为山西南部震情跟踪、流体异常核实和地震研判提供依据。研究结果显示,该热水区水化学类型主要为Cl-Na型,属中低温微咸热水。分析5个热水井样品离子相关性比值_(γ)Na+/_(γ)Cl^(-)、_(γ)Cl^(-)/_(γ)Ca^(2+)、_(γ)Cl^(-)/(_(γ)CO_(3)^(2-)+_(γ)HCO_(3)^(-)),确定各热水井的循环速度,其中:南山底半热水(NSD2)井水循环动力较强,浓缩程度较小,与冷水层交替程度较快,其余热水井循环速度由快到慢依次为中心站(ZXZ)、电力宾馆(DLBG)、南山底热水(NSD1)、温泉(WQJD)。利用同位素数据计算地下热水循环深度,并对夏县热水区热水成因进行分析,结果显示在独特构造部位和良好储水条件下,由大气降水经深循环、大地热流(地热增温)和岩石生热等作用加热,通过水—岩反应,在上升到地表的过程中与浅层地下冷水混合,并沿断裂上升出露地表,形成矿化度较高的温泉水;中心站热水井(ZXZ)开采量减少,地下水经深循环上升至地表过程中,与浅层地下冷水混合比例变大,导致其较周边热水井矿化度低、水温低,而水循环动力增强。 展开更多
