The concept and the classification of forecasting are addressed. Aiming at the disadvantages of the current forecasting models, such as requirement for more data and narrow application extent, an improved GM(1,1)-transfer function-noise model for forecasting is proposed. In the first stage, the GM(1,1) model improving the generation method of neighborhood system is adopted so as to fulfil the forecasting by only using a few of data.

介绍了预测的概念与分类；针对现有产品回收预测模型数据需求量大和适用范围窄的不足，提出了改进GM(1，1)/传递函数噪声两阶段预测模型；产品回收初期数据缺乏，主要采用改进了邻域系生成方法的IGM(1，1)模型，从而实现少量数据情况下的准确预测。

For the lack of return data in the first stage, the GM(1,1) model improving the generation method of neighborhood system is adopted, and forecasting is carried out by only using a few data. When the data amount reaches 50, the hidden quantitative relationship between sale quantity and return quantity is established by performing the transfer function-noise model. Its parameters are determined through model identification, parameters estimation and diagnostic checking. Then, forecasting return is accomplished.

回收初期数据缺乏，采用改进邻域系生成方法的GM(1，1)模型，实现了少量数据情况下的预测；回收数据累积到50个后，利用传递函数噪声模型构建了回收量和前期销售量之间的内在数量关系式，然后通过模型识别、参数估计、诊断检验确定了关系式的具体参数，进而实现了回收预测。

For an abitrary set X, appropriate order relations on WCL (the set of all weak closure operators), WIN (the set of all weak interior operators), WOU (the set of all weak exterior operators), WB (the set of all weak boundary operators), WD (the set of all weak derived operators), WD*(the set of all weak difference derived operators), WR (the set of all weak remote neighborhood system operators) and WN (the set of all weak neighborhood system operators) can be defined respectively, which make WCL, WIN, WOU, WB, WD, WD*, WR and WN to be complete lattices that are ismorphic to CS(X,CS is the set of all closure systems on X.

证明了可以在WCL(X上的弱闭包算子的全体)、 WIN(X上的弱内部算子的全体)、 WOU (X上的弱外部算子的全体)、 WB (X上的弱边界算子的全体)、WD、 WD*(X上的弱差导算子的全体)、 WR(X上的弱远域系算子的全体)和WN(X上的弱邻域系算子的全体)上定义适当的序关系，使它们成为与CS(X，〖JX-*5[JX*5]同构的完备格其中CS(X是给定集合X上的闭包系统的全体。

Based on the trophodynamics in marine ecological system and the primary productivity data from the fishing grounds of east Fujian during the marine investigation in Taiwan Strait, the concentration of organic carbon of phytoplankton and 52 species of main economic fishes were determined, and the nutritive level of the fishes and ecological efficiency in the fishing ground were calculated. The ecological carrying capacity of fish resources was 630800 tons using Cushing model and dynamics model.

闽东渔场位于26000'一27010'N、1 19050'一125000'E，北邻浙江温台渔场，南接台湾海峡，属亚热带海第2期林法玲：闽东渔场鱼类资源生态容量和最大可持续开发量域，鱼类资源丰富，系我国南方海域重要渔场之一。20世纪80年代以来，闽东渔场鱼类资源呈现衰退现象，有关鱼类资源生态容量和可持续开发量是渔业生产和管理部门所关注的问题。
