Combined GIS with MATLAB, the automatic extraction of RS and geography information of sample plots was realized.5. Introduced the resist-PCA estimation method to build the estimation formula on crown density, stock volume and diameter breast height, good forecast accuracy was achieved and the deficiency of traditional LMS parameter estimation was made up.6. The estimation process software of the model was developed, including data pretreatment, weight function selection, LMS estimation, PCS estimation, resist-PCA estimation, accuracy assessment and other function models, in order to c

摘要4、结合Gls和MATLAB技术实现对样地遥感信息和地理环境信息的自动提取。5、引入抗差主成分估计方法建立郁闭度、蓄积量、胸径的估测方程，取得了良好的估测精度，弥补了传统最小二乘参数估计的不足。6、开发了模型估测处理软件，包括数据预处理、权函数选择，LS估计，主成分估计、抗差主成分估计、精度评价等模块，实现数据处理、模型研建与精度评价的自动化、一体化。

Experimental results show that the performance of local parameter estimation is superior to that of global parameter estimation when there are no attacks, and the performance of local parameter estimation is worse than that of global parameter estimation when there are attacks.

通过实验得到以下结论：在无攻击条件下，局部参数估计的性能优于整体参数估计的性能；在有攻击条件下，整体估计的性能要好于局部参数估计的性能；压缩攻击会导致水印误检概率的增加，不同的攻击对模型造成的影响不同。

First make the subjects give either right or wrong responses to the same question with different b value. When estimating the abilities of the subjects with the use of one-parameter or two-parameter Logistic model, it is found that there exists two kinds of unfits.(2) Estimate the abilities of the subjects after introducing c parameter on the basis of the two-parameter model. The first unfit can be rectified. However, the second unfit still exists and the third unfit appears.(3) Then estimate again after introducing y parameter. It is discovered that the second unfit is rectified, but the first unfit still exists and the fourth unfit appears.(4) Form Logistic four-parameter model by introducing c parameter and y parameter at the same time and estimate one more time. This model makes all kinds of unfits, including the first, second, third and fourth unfits, rectified.

1设计这批被试分别做对或做错一道b值不同的试题，用Logistic单、双参数模型对被试进行能力估计时，发现被试能力估计存在着两类失拟现象；(2)在双参数模型基础上增加c参数，对被试进行能力估计，发现c参数能有效纠正第一失拟现象，然而仍然存在第二失拟现象，同时还存在第三失拟现象；(3)在双参数模型基础上增加γ参数，再对被试进行能力估计，发现γ参数能有效纠正第二失拟现象，而仍然存在第一失拟现象，同时还存在第四失拟现象；(4)同时增加c、γ参数形成Logistic四参数模型，再对被试进行能力估计，这时该模型对各类失拟现象，包括第一、第二、第三、第四失拟现象都具有良好拟合能力。
