本文以金冠/M9/山定子6年生树体为试材,对树体结构参数进行田间测定,用多元回归、逐步回归的方法分析出十种树体结构指标对产量的效益,用边际分析的方法和聚类的方法研究出金冠/M9/山定子产量最高时树体结构参数为:干周=24.93cm,树高=2.5cm,平均冠径=3.01m,冠高=2.5m,树冠体积=5.0~5.6m~3,单株长枝数=101~161个,单株中枝数=122—142个,单株短枝数=601~616个,单株枝量=847~903个,单株叶面积=13.5m~2。

Improving vertical resolution for density curves is by means of restructuring the response from large and small spacing sondes and borehole effect correction factor and coherence factor are used. Form the principle of GR logging, calculate volumes in investigating areas taken by borehole, formation, up and low shoulder beds, along with distance between center of gravity of the four unit bodies and detector. Based on the above, the weighting function of each unit body to GR signal contributions are established, thus realizing processing of GR logs with high resolution. The resistivity logging model uses "resolution matching" method to improve the resolution of the logs. After the process, PNN model is made to recognize the oil-gas-water bed. Compared with BPNN, the net work is featured swiftness, accuracy and ease of practical application.
