长江三角洲南部“大城市圈振兴”理论的质疑

工业发展和城市化的传统理论，对亚洲的某些具有较高生产力水平，且还在发展中的“大城市圈”不能充分地解释，本文对长江三角洲南部空间经济转为的“大城市圈振兴”理论进行了批判地评论，根据最新的现场调查结果，从根本上对“转为过程”的假说提出质疑，并且提出了更适当的的区域发展战略，此外还证明，关于亚洲大城市带的一般结论，必须建立在对地方性经济变革认识的基础之上。     

珠江三角洲工业地域分工研究

本文从专业化部门的数量和发展水平以及专业化部门地区分布和组合两方面揭示珠江三角洲工业地域分工的基本特点。指出新形势下虽然不少县市存在专业化部门多而不精，工业结构趋同的问题，但珠江三角洲地域分工格局已开始形成。文章还讨论了形成工业地域分工特点的原因并提出了完善地域分工的措施。

模糊空间分维在地震活动时空演化研究中的应用

本文把模糊分维方法应用于地震活动时空演化研究,当中.给出了强震和中强震活动模糊空间分维的确定方法,并通过计算不同小区的模糊空间分维随时间的变化曲线来研究地震活动的时空演化特征.以华北及西南地区地震活动性时空演化图象为例进行了具体分析研究.所得结果表明,大震前地震活动的模糊空间分维D_0~(2)要出现下降异常,并且大地震发生在D_0~(2)减小的地区(西南)或先减小而后达到高值(华北)的地区.     

One-station estimates of seismic moments from the mantle magnitudeM m: The case of the regional field (1.5°≤Δ≤15°)

We extend to the regional field of distances the procedure of one-station estimation of seismic moments using the mantle magnitudeM _m, as introduced earlier in the case of teleseismic events. A theoretical analysis of the validity of the asymptotic expansion of normal modes in terms of surface waves, which was used in the development ofM _m, upholds the validity of the algorithm for distances as short as 1.5°. This is confirmed by the analysis of a dataset of 149 GEOSCOPE records obtained at distances ranging from 1.5 to 15°, from earthquakes with moments between 10²⁴ and 2.5×10²⁷ dyn-cm. The performance ofM _m as measured in terms of average residual with respect to published values ofM ₀, and standard deviation of the residuals, is not degraded in this distance range, with respect to the teleseismic case. This indicates that the mantle magnitudeM _mcan be reliably used at regional distances, notably for tsunami warning applications.

Some features of the arid area variations over India: 1871–1984

Spatial variability of the annual rainfall over drier regions of India is studied by examining the variations in the arid areas. A long period (1871–1984) arid area series has been prepared for the entire country, including the two broad subregions of North India and Peninsular India, using annual rainfall data from 306 well distributed stations. Following an objectively determined criterion based on rainfall amount alone, the yearly area under arid conditions is obtained by totalling areas which received annual rainfall totals less than 560 mm. The interannual variability of the arid area series is large and its distribution is highly right-skewed, demonstrating large spatial variations in the annual rainfall over India. Statistical tests do not suggest any significant long-term trend in the arid area series, but persistently low values of the arid area after 1941 are noteworthy. Implications for the study of risk analysis and assessment of drought and desertification processes are discussed.
