To deblur edge after image magnifying,an adaptie edge sharpness presering image magnification is put forword,which can fit edges of any direction,gradient and amplitude,utilizing the gradient imgormation of the image and the properties of the hyperbolic tangent function haing reiewing the character of a typical edge.

针对图像放大后出现边缘模糊的现象，论文考察了典型边缘的特征，利用图像的梯度信息和双曲正切函数的性质，提出了一种较好地拟合任意方向、陡度和幅度的边缘，因此能够保持边缘锐度的自适应图像放大算法。

For such reasons, the author investigated comprehensively on cropping systems and agriculture development in Fenxin County from 2002 to 2004, using mathematics model and GIS, discussed the cropping systems characteristic and development orientation and optimized the cropping systems spatial distribution. The data were collected from literature, questionnaires to experts and farm households, on-site investigation and field experiments. The main results are as follows:1,Because of inconsequent exploitation and management of the resources, rapid increasing population in hilly region of red soil, the stress on soil, deterioration of farmland ecological environment and soil gleization become more and more serious. Natural features , water and thermal resources and species are abundance.

基于以上目的，作者于2002-2004年，通过资料调研、专家咨询、农户调查、实地考察和田间试验等手段，对江西奉新县的种植制度和农业发展进行了全面的调查，通过建立数学模型和运用地理信息系统，对奉新县的种植制度的特征和发展方向进行了全面的论述，并且对种植制度进行了空间布局优化，主要结果如下： 1、红壤丘陵区由于长期以来对资源的不合理利用和掠夺式经营以及人口的急剧增长，土地压力上升，农田生态环境恶化，土壤潜育化，土壤肥力退化非常严重，但区内自然条件优越、水热资源总量丰富、物种丰富，具有一定的区位优势，为区内种植制度调整提供了有利条件。

The intersecting positions of aeromagnetic lines of different directions and depths were calculated, and characteristics of the integrated anomaly of different elements were described. The fuzzy membership map for the porphyry copper deposit was compiled.

通过模糊推理计算得到该区不同高度、不同方向航磁解译构造的交汇部位以及不同元素的组合异常特征，最终确定了该区可以发现斑岩型铜矿的模糊概率分布图。

Researched the reservoir developed feature and changing regularity laterally,predicted the reservoir distributing regularity,established the reservoir geological pattern, synthetically evaluated and predicted good reservoir distribution and favorable exploring goal .point out that the reservoir interzone was fissure-pore type, outer zone were fissure-hole and cave types,what was significant to the next exploration.

对单井剖面的储层发育特征，储层横向变化规律的研究，分析预测了储层的发育分布规律，建立了储层地质模型，综合评价预测了优质储层的分布和有利的勘探方向，指出内带主要以裂缝—孔隙型储层为主，外带以裂缝—孔洞型、孔洞型储层为主。这对该区的下一步勘探具有重要的现实意义。
