采用实地调查、统计年鉴资料和区域差异分析等方法,对区域GDP总量、财政收入和居民生活水平,以及三次产业结构作比较分析。结果显示,广东区域发展失衡、经济水平悬殊、产业结构不协调、环境压力加大;在此基础上,通过产业和劳动力的空间双转移形式,带来工业产值增长的经济效应,扩大人口就业的社会效应,减轻环境压力的生态效应,达到经济要素结合的空间效应,但仍存在以行政力量和政区为主导与框架、市场调控乏力,转移空间狭小、劳动者素质偏低等问题。就此提出建立合理的产业地域分工体系、提升和协调四大经济区水平与区域关系,扩大双转移范围,发挥华侨、港澳作用,加强劳力培训等改进与完善双转移的对策和措施。 相似文献

The Pilot Small Telescope Network (PSTN) is a state‐of the art system of easily replicable and scalable hardware, software, servers, eXtensible Markup Language (XML) protocols, and network middleware connecting and developing a pilot array of robotic telescopes to one another and the user community. The PSTN is a developmental project that will allow growing access to these telescopes, and make available data to faculty, students and others in an environment of collaboration. The underlying goal of the PSTN is to broaden the quantity and quality of astronomical education and research, particularly with a focus on traditionally underserved populations.

-In this paper, the maximum entropy spectral, the cross-spectral and the frequency response analyses are madeon the basis of the data of monthly mean sea levels at coastal stations in the Bohai Sea during 1965-1986. The results show that the annual fluctuations of the monthly mean sea levels in the Bohai Sea are the results of the coupling response of seasonal variations of the marine hydrometeorological factors. Furthermore, the regression prediction equation is obtained by using the double screening stepwise regression analysis method . Through the prediction test , it is proved that the obtained results are desirable. 相似文献

The long-term time series analysis of the SST (sea surface temperature) in the Eastern Equatorial Pacific Ocean and the monthly MSL (mean sea level) in the tropical Pacific Ocean is conducted. Their quasiperiodic and low-frequency oscillation features are revealed. The significant periods of low-frequency fluctuations for monthly MSL in the area of 20°N-20° S are between 43. 5 months and 50. 0 months, approximating closely to 47. 6 months which is the significant period of SST in the Eastern Equatorial Pacific Ocean. From the results of space-spectral analysis, the low-frequency fluctations of monthly MSL in the tropical Pacific Ocean appear to have a anticlockwise circularly-propagating pattern, which is, the Eastern Pacific Ocean (off-shore of Mexico) →the area of NEC (North Equatorial Current) →the Western Equatorial Pacific Ocean→the area of NECC (North Equatorial Counter-Current)→the Eastern Equatorial Pacific Ocean. The phases of the pattern correspond to those of El Nino cycle. On the basis 相似文献

明末清初广东人屈大均著《广东新语》是一部关于岭南历史地理杰作，涉及自然、经济、文化、聚落、民族地理等部门、内容丰富，见解精到，有很高的学术价值。但在中国地理学史上长期湮没无闻，实有失公允。在人文地理学复兴的今天，应重视对该书的研究，给屈大均其人其书予应有历史地位． 相似文献

-In this paper,by using ISODATA of fuzzy cluster,the water masses classification of the upper layer in the E-quatorial Western Pacific is carried out. On the basis of the degree of the membership in the obtained optima) classification matrix, the solid distribution of the detailed structure of water masses is made. The water of the upper layer,consisting of six water masses,may be divided into three layers,i, e. ,the surface,subsurface and intermediate layer. Besides analyzing the features of various water masses,a discussion on their distribution structure and formation mechanism is also made. 相似文献
