从政策破茧到市场嬗变——2006年我国土地市场综述

2006年的土地市场分为两个层面,从实体的方面看,土地市场供求关系略虽显偏紧,但没有太大起伏,比较平稳。从政策层面看,土地市场环境发生了重大的变革,其力道之大,为1990年国务院55号令以来所罕见,非常的波澜壮阔,隐喻着2006年将成为土地市场发展的一个新的历史拐点。土地市场运行环境趋紧2006年我国土地市场运行环境总体偏紧。从大的宏观背景看,在“十一五”期间,全国要求保有耕地18亿亩,这个任务非常艰巨。这一宏观局势不仅决定了2006年土地市场新增的供给要受到更加严格的约束,而且决定了在今后相当长的一个时期内,土地市场的供给要受到越…

地图产品如何适应新形势?

地图是国家版图的主要表现形式之一,体现了国家在国际社会中的政治、外交立场、领土主权和民族尊严,具有严肃的政治性,严密的科学性和严格的法定性。地图以其庄重、直观、易读的特点,在经济建设和社会生活各个方面发挥着重要作用。随着经济的快速发展,社会的全面进步,人民生活质量的不断提高,社会各方面对地图产品提出了更高的要求。我国加入WTO后,测绘市场虽然未承诺对外开放,但许多与测绘有关的市场均已对外开放,这将间接影响到测绘市场包括地图市场,如发行市场的开放,国外商家在我国建立自己的销售发行网络,这将冲击我国现行的地图发行…

Numerical study of the seasonal salinity budget of the upper ocean in the Bay of Bengal in 2014

Impact factors on the salinity budget,especially the eddy salt fluxes and smaller-scale diffusive salt fluxes for the upper 50 m of the Bay of Bengal(BoB) in 2014 are investigated using a box model based on the Regional Ocean Modeling System(ROMS) daily outputs.The model results reproduce that the precipitation and river runoffs are the dominant factors modulating the sharp salinity decrease during the summer monsoon season.The analysis shows that the salinity increase after the summer monsoon is mostly due to the meridional advective and diffusive salt fluxes.The vertical advective salt flux,which is sensitive to the different signals of the wind stress curl,plays an important role in balancing the salinity change induced by the meridional advective salt flux during both the summer and winter monsoon seasons.Distinctive spatial mesosc ale structures are presented in the eddy salt flux throughout the year,and their contributions are sizeable(over 30% in the meridional direction and about 10%-30% in the vertical direction).The meridional eddy salt flux is larger in the monsoon seasons than that in the inter-monsoon seasons,and in a positive pattern near the western boundary during the winter monsoon and autumn inter-monsoon.The vertical eddy salt flux makes an important contribution to the salinity budget,especially along the coastal area and around the Andaman and Nicobar Islands.The vertical eddy salt flux becomes large when a tropical cyclone passes the area.

Changes in the network of tourist trails in the border zones of the Czech Republic after entering the Schengen area

Among the factors influencing tourist trail network development are political issues, including the presence of state borders, the possibility of crossing them and the accessibility of border zones. In the article, it was decided to look at changes in the offer of tourist trails(hiking and cycling) along the entire border of the Czech Republic after the extension of the Schengen area(within this area, crossing the border is possible anywhere, and not only at official border crossings). It should be emphasized here that the borders of the Czech Republic over most of their length run through mountainous areas and, apart from political factors, natural features should have a major impact on the development of tourist routes. In order to determine the coherence of the current network of trails on both sides of the Czech Republic state border, modern tourist maps have been analyzed, determining the number of places where it is possible to cross the state border with the help of a marked tourist trail. Based on that, two indicators were introduced to determine the degree of openness with all neighboring countries as regards the opportunity to cross on a tourist trail. Changes in the historical situation, a comparison of the accessibility of the border area before entering the Schengen area and 2019, were analyzed for two study areas using archival maps. Over a decade after the extension of the Schengen area, the number of places where tourist trails of neighboring countries approach the border has clearly increased. Crossing is more often made possible using hiking trails than cycling routes(trails of the first type cross the border every 7.91 km, while the latter every 13.3 km), but considering the speed of movement, it can be assessed that the openness for cyclists is higher than for hikers. Moreover, in many places there is still significant potential for further integration of tourist trail networks as trails created in one country often do not have a continuation on the other side of the border.

Assessment of Habitat Suitability in the Upper Reaches of the Min River in China

Habitat richness influences and even determines biological diversity. Plant habitat suitability assessment can provide technical guidance and information support for ecological restoration. Thirteen factors in three categories of terrain, meteorology and soil were chosen to build a habitat suitability assessment index framework in the Upper Reaches of the Min River, based on the local natural environment and the actual influencing factors of vegetative growth. Combined with the Analytic Hierarchy Process(AHP) and entropy method, which were used to calculate weights of indexes, habitat suitability was studied by using a multi-objective linear weighting model and geographic information systems(GIS) spatial analysis techniques. The assessment results are as follows: Altitude, soil stability, aspect and slope have more important effects on plant habitat suitability in the Upper Reaches of the Min River, and their weights are 0.311, 0.260, 0.198 and 0.125, respectively. Suitable and sub-suitable habitats cover 4431.80 km2 and 6171.12 km2, respectively; most of which are distributed along both sides of rivers and have higher suitability. Unsuitable habitats cover the largest area(6679.76 km2), accounting for 29.83% of the whole area; and the worst unsuitable habitats are 5107.23 km2(22.81%); they account for more than half of the studyarea. These results indicate that the plant habitat in the Upper Reaches of the Min River is poor and ecological restoration is both urgent and difficult. Therefore, based on the principle of taking measures suitable to the habitat in ecological restoration projects, ecological and engineering measures should be combined to have better effects, while increasing the strength of ecological protection.     

鱼虾混养池中蓝藻群落结构及其微囊藻毒素含量变化

对广东省中山市三角镇的低盐度鱼虾混养池进行连续采样分析,结果表明,混养池中的蓝藻主要有螺旋藻(Spirulina sp.),鱼腥藻(Anabaena sp.),颤藻(Oscillatoria sp.)、铜绿微囊藻(Microcystis aeruginosa)等,其中盐泽螺旋藻的优势度为0.52~0.73。蓝藻是水体中的优势微藻种群,蓝藻细胞数量占微藻细胞数量的88%~99%,蓝藻细胞数为0.99×10~9~5.89×l0~9 cell/L。混养池微藻多样性指数(H’)为1.16~2.49,养殖水体处于中度污染状态。溶解性无机氮的质量浓度为0.13~2.30 mg/L,正磷酸盐质量浓度为0.25~2.39 mg/L,化学需氧量的质量浓度为1.94~13.79 mg/L。微囊藻毒素(MC-LR)在水中质量浓度为0.18~0.79μg/L。蓝藻细胞数量与化学需氧量之间呈显著的正相关关系,表明蓝藻的生长情况与养殖池中的有机污染程度有密切联系,低盐度的富营养化的水体能促进蓝藻的生长,成为微藻群落中的优势种群。MC-LR的质量浓度与蓝藻细胞数量之间无显著相关。     

Characteristics of the transition Layer in the South China Sea in 1998

CTD data on standard levels coolected during July and December in 1998 and the cubic spline interpolating method were used to study the characteristics of the transition layer temperature and salinity.The thermocline undergoes remarkable seasonal variation in the South China Sea (SCS),and especially in the region of the north shelf where the thermocline disappears in december.The thermocline is stronger and thicker in July than in December,There is no obvious seasonal variation in the halocline.Due to the upper Ekman transport caused by monsoon over the SCS,the thermocline slopes upward in July and downward in december from east to west in the northern SCS.The characteristics of the thermocline and halocline are influenced by local eddies in the SCS.The Zhujiang diluted flow influences significantly the SCS shelf‘s halocline.     

Contrast between the climatic states of the warm pool in the Indian Ocean and in the Pacific Ocean

Based on the analysis of Levitus data, the climatic states of the warm pool in the Indian Ocean (WPIO) and in the Pacific Ocean (WPPO) are studied. it is found that WPIO has a relatively smaller area, a shallower bottom and a slightly lower seawater temperature than those of WPPO. The horizontal area at different depths, volumes, central positions, and bottom depths of both WPIO and WPPO show quite apparent signals of seasonal variation. The maximum amplitude of WPIO surface area’s seasonal variation is 58% larger over the annual mean value. WPIO’s maximum volume variation amplitude is 66% larger over the annual mean value. The maximum variation amplitudes of the surface area and volume of WPPO are 20.9% and 20.6% larger over the annual mean value respectively. WPIO and WPPO show different temporal and spatial characteristics mainly due to the different wind fields and restriction of ocean basin geometry. For instance, seasonal northern displacement of WPIO is, to some extent, constrained by the basin of the Indian Ocean, while WPPO moves relatively freely in the longitudinal direction. The influence of WPIO and WPPO over the atmospheric motion must be quite different.
