Abstract
The macroscopic effect of remote sensing Geoinformation is one of the important properties of remote sensing information. The excellent macroscopic capacity feature helpful to research on geosciences objects.

Comparing to the big capacity of different remote sensing resolution scales, the levels of comprehensive application of remote sensing information are relatively low. It is a common thought that remote sensing information only complements common Geoinformation p[partly and remote sensing techniques do the same thing to common exploration methods. At present, with the development of new spectral imagery and Radar imagery techniques, NM-level object spectral features and various kinds of modular space structure information may be identified from the imageries. People are willing to find deposits directly, while ignoring the research on macroscopic effect of remote sensing. The Earth System is of a complex macroscopic knowledge system, space information system is of a typical layer and network frame, and macroscopic effect is central for the Earth system science. In recent years , there come the research fun of large-super-large ore deposits, the research fun of the relationship between large scale mineralizing and large scale mineralizing collecting areas, and the prominent research fun of mantle plume. All the funs about middle-large scale structure and mineralizing, relative to the Earth movement , are have intense relation with the macroscopic Geoinformation. To study the physical principles of the macroscopic effect of the remote sensing Geoinformation and search for the effect's relation ships with regional mineralizing is challenging topic and development trends of present solid resource remote sensing.

Introduction
With the development of remote sensing (RS) technology, the RS of mineral resource has revolved more deeply. For a long time, people have been customary to the programs of geological remote sensing, such as RS data collection, image processing, image enhancing, explanation, field test, and applied RS tech. To each stage of mineral resource exploration in order to help mineral prospecting. It is a helpful method to overlay three kinds of information, RS, geophysics and geochemist information. But the comprehension and the application of RS information are far less that the ability of RS technique, which is usually regarded as one kind of compliment to the routine Geoinformation and exploration methods. Especially, with the new development of sensors, NM-level object spectral features and various kinds of modular space-structure information may be obtained by spectral imagery and Radar imagery techniques, even alterative minerals may be identified from the imageries. People are willing to find deposits directly , while ignoring the research on macroscopic effect of RS. Ore deposit does not exit along, mineralizing does not exit in part region along, and each mineralizing element, as one kind of mineral in the earth participates in global structure movement and mineralizing function with other elements. Apart from to adopt modern Earth observation techniques fully , to collect microscopic rock and mineral information, and to study microscope substance composition principles, the study of mineral resource RS should be dig full large-space-scale metrication Geoinformation deeply , and to build application theories, techniques and methods of the specialty. There are a few samples of studying global structures and ore distribution by using space fight RS information. What's more, at recent years, there comes the research fun of large -super-large ore deposits, the research fun of large scale mineralizing and large scale mineralized collecting areas, and the promineralized collecting areas and the prominent research fun of mantle plume. All the funs about middle-large scale structure and mineralizing, related with the Earth movement, area have intense relation with the macroscopic Geoinformation. To study the physical principal of the macroscopic effect of the RS Geoinformation . To study the physical principals of the macroscopic effect of the RS Geoinformation and search for the relationship of the effect with regional mineralizing is challenging topic and developing trends of present solid resource remote sensing.

1. The Double phenomena of the space Feature of RS information
It is a common thought that the resolution of RS is the key discriminate object . The higher the resolution, the stronger the ability to solve problems. Therefore, apart from both to enhance spectral and space resolution, and to improve imagery spectral technique and high-resolution Radar space techniques, men are devoted to the study of decompose-pixel technique. Modern RS may be regarded as a pixel-detecting technique, based on detecting units. Some researchers are trying to apply some physical principles on basic particles to interpret RS physical principles, then to build pixel-scale RS basic theories and system of RS techniques and method, supported by present RS techniques and method on information obtainment, image processing and information extraction. While, the RS system are facing on challenge from the mineral resource RS exploration. It is an undeniable fact that while the RS resolution has been enhanced greatly, while there are no breakout on exploration theories, technical method and exploration effects of mineral resource RS. One reason of the fact is due to the microscopic and macroscopic effects of RS information, called the double effects of RS information, The later effects is usually ignored in the common study, while the former is weighted. But, in accordance with the similarity in both the space scale and time scale of the macroscopic effects of RS and the mineralizing function, the macroscopic effect is more suitable to macroscopic exploration study.

Microscopic Effect: All substance on the Earth is composed of kind of rocks and minerals. When using RS data, man pays more attention to minerals information then to rock information. For, in space scale, minerals are more attention to mineral are more approximate to microscopic particles, molecules, atoms, ions, electrons, the physical properties and the spectral properties of which may be used to study the microscopic principles of rock compose and to build feature spectrum database for discriminating minerals. Pixel-spectrum decomposition technique can decompose each end number to sub-pixel scale, and present rock properties in precise approximation to the weight of each end number. Imagery spectrum technique has unified mineral images and the corresponding spectrums, using spectrum match to discriminate mineral directly in the spectrum dimension. All the theories and method based on pixel scale objects, embody the macroscopic effects of RS information space.

Macroscopic Effect: The macroscopic effects of RS information is obvious. If a little-scale image is compared to a reduced big-scale image of the same area it is easy to find that two images represented the same object are not same completely. For example, in kinds of RS imageries, it is difficult to find the imagery feature, corresponding to a structure trace shown clearly on NOAA imagery. The trace is difficult to be found in middle-scale TMs scenes. It is nearly non-existing on large-scale aero-RS imageries. Stratums of various rocks may appear as one imagery of similar hue. Directly heterogeneous rocks appear as imageries of the same hue and texture. Such phenomenon is normal in the nature. We may simulate such thing on computer: use randomly various spectrums of objects as background, object information is added (an irregular white spot), then change the scale of the image gradually, and object information is shown more obviously. In figure (a), the irregular white spot is similar to letter c, and is overlaid by a cross form; while the form of letter c has been similar to a polygon in figure (b), and become a punctual white spot. In such an experiment, the shrinking of image scale is largely equal to the changing of space measure, suppressing high frequency noise and enhancing low frequency information. The experiment shows that the macroscopic effect of RS information is actually existing.

Having studied the BRDF property of vegetation, Xiaowen Li found that some physical principles of electromagnetic wave, for instance, Beer principle, had been unavailable when the proportion of RS resolution and the measure of vegetation leaf surface, in addition to vegetation spacing, changed. So, he believes there is a 'measure effect' problem of electromagnetic wave of object, which has been proved by Li-Strahler Model that object in pixel-scale space is a Lombard object, or not a Lombard object in a larger space than pixel scale (Xiaowen Li, 1999)1 [1]. All above shows that various scale RS information has various spectral features; the macroscopic and microscopic effects are two sides of object properties and can not be obtained by simple composition or decomposition progress.
