  regional trend
The rates of soil ammonification (66.8 to 84.1 kg N · ha-1 · yr-1) and amounts of total N mineralized (103.7 to 130.6 kg N · ha-1 · yr-1) did not show a clear regional trend across the gradient sites.
      
In these deposits, gold mineralisation is located in faults that parallel the regional trend of the belts and were active late in the deformation history of the terrane.
      
In addition, the integrated numerical model is capable of simulating the regional trend of potentiometric levels, land subsidence and salt concentration.
      
Range and regional trend of the modeled temperature values are in agreement with the published data.
      
No significant regional trend in BNPP-C was found.

  range trend
The results suggest that the wavelet variogram can filter out the effects of long-range trend, but not local trend, and of transitions from one class to another, as across boundaries.
      
The long-range trend in the solar wind velocity during the 11-year cycle is governed by the number and intensity of irregularities occurring in the corona.
      
Additionally, footwall width perpendicular to range trend may also control overall relief.
      


This paper reports an attempt to use fuzzy mathematics as a tool for forecasting the regional population fluctuations of yellow rice borer for moderately long term in Ji-an,Jiangxi,by selecting the forecasting fac- tors conventionally,and applying a number of techniques such as multi- factorial evaluations,fuzzy relation equations and fuzzy preference ratio. The procedures and results are given.

The broad beau aphids is a mixed population consisting of aphids craccivora Koch,Acyrfhosiphon pisum(Harris)and Megoura japonica(Matsumura).Extent of its incidence is described with 5 grades,i.e., slight,moderate,heavy,moderateand moderate ̄+.During the broad beau growing season, there is obvious repeatedness of the aphid occurrence in a certain area among years.Because of this,the"fuzzy preference ratio"is chosen as a basic method for prediction of the range trend of broad beau aphid occurrence.Seven prediction factors that closely correlate with the incidence of the pest and have omenous characters are used to predict occurrence trend for the next year.From 1993 to 1995.the method has successively been used for 3 years with the predictions.And a comparatively satisfactory solution of the problem concerning long-term prediction of broad beau aphid occurrence has thus come into ekistence.

蚕豆蚜为豆蚜MphiscraccivoraKoch、豌豆蚜Acyrthosiphompisum(Harris)豌豆修尾蚜Megourajaponica的混合种群,其发生程序用轻、中、重、中偏轻、中偏重5个级别进行描述。在蚕豆生长的季节里,一定区域内,同一发生程度年度间存在着明显的重复性。据此选用“模糊优先比”作为蚕豆蚜发生区域趋势预测的基本方法。用与发生程度密切相关,并具有先兆性的7个因子,对翌年蚕豆蚜发生趋势进行预测。经1993~1995连续3年应用,预测与实况均相符,较好地解决了蚕豆蚜危害的长期预报问题。
