发布时间：2021-06-10 - 摘要：The scope of applying the quantified theory in the field of natural science has been expanding increasingly since 1960s. This paper overviews the developing trends of the table-making techniques for quantified airphoto stand-volume tables in the past ten years, describes the general mathematical expression and the table-compling skills used in the process of making airphoto stand-volume tables by utilizing the Quantitative Theory I in the forest resource inventory based on the characteristics in each stage, demostrates the coefficients of partial correlation between 20 table-making factors in different forest areas and unit stock of stand, discusses the problems such as the selecting, extracting and filtering principles of table-compiling factors, reasonable classification of category series, quantified stand-volume tables of single discrete independent variable, discrete and continuous mixed independent variables actually used in practice. The paper concludes that the techniques using airphoto to compile quantified stand-volume tables has been already shown as a practical tools in forest resource inventory. The actual application will create obvious economical effects by improving the quantity of forest resource survey, speeding up the inventory speed, decreasing the inventory cost and reducing labour intensity.

发布时间：2021-06-10 - 摘要：In the Tai-hang and Kunlum Mountain areas, on the satellite images the structural and imagery features are shown in the lens-like compression tectonic mass, it can be summarized as following: large dimension, regularity in form of lens-like, all margin made by faults or shearing fracture zones, obvious lineament features, and uniform genesis in a stress field which is most important for those structural features.On the basis of the field survery and interpretation of remote sensing imagery, the genesis of Tai-hang Mountain under the NW-SE trend horizontal compression in Meso-zoic Era.It is significance ot those masses: 1. it may indicate the orientation of the areal compression stress, and 2. it might be imagery symbol of strong collision between the plates or of the intraplates.

发布时间：2021-06-10 - 摘要：SIR-A and SIR-B images or three sand dunes and two bedrock regions in Alashan Plateau of north central China have been studied and compared to the digital processing Landsat imagery and field investigation data. The results of the study show that radar illuminating direction is a key factor, which results in the echo strength change for the same type and size of sand dunes. The sand dunes in which the slipfaces are oriented to radar beam have a bright-point response and the dunes in which the gentle slopes face the radar beam have a dark signature on the radar images. Two Precambrian metamorphic rock bodies buried beneath the thin layer of alluvial material or aeolian sand have been detected by using the spaceborne radar imagery. A preliminary scattering model was given to explain the imaging mechanism.

发布时间：2021-06-10 - 摘要：The IRSA-2 digital image processing system was developed by the digital image processing laboratory, institute of remote sensing application. The system consisted of ECLIPSE S140 computer, COMTAL image display and digital image processing software.IRSA-2 system has perfective image management suboperation system, image processing application programs and multiuser capability. Both MENU mode and command line mode of operations are available. It is transferable and expansible.Upon being completed by the end of 1984, the system was evaluated as a advanced and successful computer digital image processing system by a lot of scientists in Academic Sinica. Its higher reliability and effeciency have been proved during its over one year serving operation.

发布时间：2021-06-10 - 摘要：The experience in the past years or image processing snows a tew geological information in the plain area. Conventional contrast enhancement gives monotonous hue that would not reflect geological subject properly. Authors suggest performance of enhancement at spectral dimensions. The nature of suggested technique is extension of the differences in the brightness values of named pixel at the three spectral dimensions which are involved in the composition that makes the named pixel more bright-colored, i.e color-enhanced. Such processing method changes the subtle differences between the brightness of the diverse objects in the image into obvious differences in the colors. The geological information can be enhanced in this way.Performance of spectral-dimension enhancement requires two terms. The first is that the brightness values of the named pixel must maintain the same relationship, i.e, the bigger value must be remained bigger after enhancement; the second, sum of the brightness values at the three dimensions must be remained the same as before enhancement, so that the only operation in the enhancement is extension of the differences in the brightnesses at three spectral bands. Therefore, the method provides the specifications of a standard false color composite and, simultaneously, a bright-colored, information-enriched image.

发布时间：2021-06-10 - 摘要：A new remote sensing technique for sugarcane yield estimation is described. The main instrument used in the study is Hand Held Ratioing Radiometer and spectral quantity is the reflectance ratio TM3/TM 4. Spectral measurements for sugarcane yield estimation were conducted in matured stage of the crop. In test area 10 plots of sugarcane field which amount to 500 mu （about 34 ha.） were selected as test samples. The results of regression analysis showed that there is a high correlation between X （reflectance ratio TM3/TM4） and Y （per mu havrest yield）. The correlation coefficient is as high as 0.9431. The optimum mathematic model for sugarcane yield estimation was proved to be Log Y= a + bX. The calculation of relative error indicates that the yield estimation accuracy of remote sensing technique is twice as high as that of the traditional artificial method.

发布时间：2021-06-10 - 摘要：Air-photo is real image of ground scene in which there is plenty of imformation about landscape. By applying air-photo, it is possible to interprete soils. In air-photo interpretation of soils, the soil genesis grouping, soil information factors are connected with its image characteristics in photo according to the identity of soil distribution and bioclimate environment, the principal interpreting elements in different degree of soils grouping system is determined by using the image characteristics of topography, of plant cover and of hydrological condition in photo, which possess special effect on soil formation and can reflect soiltypc. By overall analysis of photo, the interpretation of soilgroup, soil subgroup, soil family and soil species can be done in surveyed region. In general, soils type above soil family degree can be interpreted by photo. For some of soils, even the soil species can be interpreted by photo. The air-photo interpretation of soils can meet the requirment compilation of mid-scale or small scale soil map. In soil-surveying, the field work can be less, the time for mapping shorter, the accuracy of mapping higher by applying air-photo.

发布时间：2021-06-10 - 摘要：<正> 目前,我国水产品总产量居世界第三位,其中海洋渔业捕获量的90％取于近海。由于过度的捕捞,造成近海底层鱼类资源严重衰退。当务之急是积极开发外海、远洋渔业,建立海洋水文、水质监测以及渔场、渔情的测报预报体系。从我国现有的渔业生产能力来看,若以建立渔情测报体系后,可减少找鱼在航时间10％、增加渔获量2％计算,每年可节油12万吨,可多捕鱼5.6万吨,总收益每年近8,000万元。因此,远在七十年代初,有关海洋与水产部门就开始关注航天和航空遥感应用于海洋渔业生产,并开展了探索性的实验研究。
