关键词： 影像资料   地理国情普查   地理国情监测   技术水平   信息获取   目标对象   区域治理   地理信息  

摘要： 随着技术水平的不断提升,从2016年开始,在第一次全国性地理国情普查的基础上,逐步尝试进行地理国情监测常态化体系的建设,构建基础性地理国情监测新机制。基础性地理国情监测脱胎于全国地理国情普查,监测范围较广,面向的目标对象较为多样,能够满足不同场景下,多元化的地理信息获取和使用需求。同时在相关技术的持续支持下,基础性地理国情监测的实时性、准确性得到稳步提升,由于其将地理信息与国情相关要素进行动态结合对比,并通过影像资料等呈现方式,将监测到的各类数据信息直观呈现在相关工作人员面前,进而为领导决策、区域治理、督察监管等工作的开展提供了数据支持。

关键词： air temperature   high temperature   low temperature   temperature amplitude   temperature maps   temperature vulnerability  

摘要： Air temperature conditions affect various aspects of human life through diverse pathways, such as health, agriculture, labour productivity, infrastructure and building constructions, economic production, and so on. To address better efforts at resolving this issue, decision-making tools need to be developed to identify and prioritize areas where appropriate actions are required. The present paper identifies vulnerable areas in Morocco with a focus on three different aspects: high temperatures, low temperatures and daily temperature amplitude. Maps were created using the National Oceanic and Atmospheric Administration (NOAA)-developed Climate Forecast System Reanalysis (CFSR) 30 year-long daily maximum and minimum temperature data set. Several indicators as well as vulnerability indexes were defined and calculated. Maps showing the spatial distribution of these indicators were created. The results show that 78% of Morocco is considered to be non-vulnerable areas to areas with low vulnerability;and 19% is characterized by moderate vulnerability to the effects of temperature. The remaining areas are characterized by high to extreme vulnerability: the most vulnerable areas are located in the provinces of Figuig, Jerada and Boulemane in the eastern part of the country, as well as in the provinces of Khouribga, Fquih Ben Saleh and Settat in the central part. This implies, for example, that national-level planners in the agriculture and transport/infrastructure sectors in the central part need to take into account temperature vulnerabilities as they develop sector strategies and plans.

关键词： Geographic Information System   Remote Sensing   Land cover change  

摘要： In this study, an effort has been made to assess the changes in land cover in some municipalities and cities of Nueva Ecija. The study was carried out through remote sensing and GIS approach using Landsat Images (Landsat 4 TM, Land Sat 7 ETM+, Landsat 5 TM, and Landsat 8 OLI_TIRS). For this purpose, a supervised classification technique was applied to Landsat images acquired in 1989 to 2018. Results indicated that land cover changes have occurred in agricultural, urban, and forestry areas which happened in the study areas from 1989 to 2018. Urban areas, although covering a much smaller proportion of the landscape/land cover in both time periods, increased at a much higher rate than any other land cover classes. The increase in agricultural and urban areas mostly result in deforestation, which means some forest areas were removed and converted to agriculture and settlement in the municipalities/cities.

关键词： Coefficient of variation   Comprehensive comparative advantage   Geographic information system   Pig production   Resource endowment index  

摘要： China's pig production ranks first in the world. However, keeping a continuous and rapidly sustainable development is difficult due to the dual constraints of environment and resources. To solve this problem, the key regions that have high comprehensive comparative advantage value of pig production and development must be determined. Therefore, this study established a comprehensive comparative advantage index system and a comprehensive comparative advantage model of pig production and development. On this basis, the comprehensive comparative advantage value of pig production and development was calculated, and the key pig production and development regions were selected using (geographic information system) spatial analysis technology. The potential quantity of pig production in the key pig production and development regions were estimated according to the European Union standard for limitation of nutrient load of farmland from livestock manure. Results showed that the largest comprehensive comparative advantage value of pig production and development in China was 0.58 in Heilongjiang, followed by 0.55 in Sichuan, and 0.25 in Beijing, which was the smallest. The 11 provinces selected as the key pig production development regions in China were consistent with the key development regions or potential growth regions defined in the National Pig Production Development Plan 2016-2020. The Inner Mongolia had most potential quantity of pig production, followed by Sichuan. The results of this study could provide support for the spatial layout planning of pig farming and the rational allocation of regional resources. Graphic abstract [GRAPHICS] .

摘要： Understanding spatial variation of rock and soil is important for capability precision as well as groundwater contamination or geopollution management. In view of waste dump/landfills, geoenvironmental hazards ravaging our land including surface and groundwater contamination, site suitability indexing, spatial distribution and characteristics of underlying rock and soil matter are studied. Rock and soil samples were collected in a systematic grid pattern using simple drill core rig and hand auger. Geostatistical and soil property analyses were conducted on each grid. Groundwater aquifer vulnerability to leachate was studied using depth to water table, recharge (precipitation), aquifer material, topographic slope, impact on vadose zone/vadose zone material and hydraulic conductivity (DRASTIC) and geophysical methods. Human population growth analysis indicates tremendous waste generation. Flash points of waste generation and dumping were noted. Geographical positioning system was used to take record of sampling point coordinates. Using a sufficient dataset, each grid indicative factor is objectively scaled, weighed and assigned a numerical rating according to their relative importance employing site suitability (S) analysis approach in an empirical equation. Results were imported into a geographic information system (GIS) platform to generate thematic maps. The results showed that subsurface rock and soil characteristics are neither spatially nor vertically homogeneously distributed. Thematic maps were generated and further interpolated in the GIS domain to produce a composite waste dump/landfill suitability index map.
