Based on the data of urban land use obtained by remote sensing interpretation from aero images in 1986 and 2.0{3. the spatial structure of Jinan is studied in this paper with the method of Geographic Information System ({2.). According to the proportion of land for residence, industry and commerce, the urban district can be distinguished into three rings. Compared with the traditional theory of the ring structure in Western coun- tries, they have many distinctive characteristics. The main func- tions of the inner ring include residence, business and banking, but the proportion of residential land (more than 50%) is considerably higher than that of the cities in Western countries. The land proportion for residence and industry in the intermediate ring is equal on the whole. The main land of the outside ring is for industrial use. From 1986 to 2.0{3. great changes have taken place on the land proportion of different types of use. In the inner ring, the land for residential and industrial use has shrunk much while the land for commercial use has increased. In the intermediate ring, the changes of the three types of land use were not very much and the temporal variation was relatively stable. On the contrary, the structure in the outside ring varies acutely. Though most of it is also for industrial use, the proportion of residential land has in- creased much. The three rings can also be divided into several sectors respectively, according to the function of land use clusters. New trends and mechanisms of the changes of land use impacting the urban structure were proposed in the end of the paper.

An exponential relationship between net primary productivity (NPP) and integrated NDVI has been found in this paper. Based on the relationship and using multi-temporal 8 km resolution NOAA AVHRR-NDVI data, the spatial distribution and dynamic change of NPP and fractional vegetation cover in the Yellow River Basin from 1982.to 1999 are analyzed. Finally, the effect of rainfall on NDVI is examined. Results show that mean NPP and fractional vegetation cover have an inclining trend for the whole basin, and rainfall in flood season influences vegetation cover most.

4. products are basic mode of digitized products that are made by combining model remote sensing with {{3. technology, and have already brought everybody’s high recognition. Coal mining makes great destroy to land of coal mining area, and ecological environment becomes worse, therefore land reclamation of mining area has already turned into investigated emphases. 4. meaning is briefly introduced, and its six characteristics are expounded in this paper. Production technique and application status of 4. are summarized, and existed problems are analyzed in developed aspect. Land reclamation of mining area is a complex system engineering, and application of 4. products can be impenetrated in whole process. Otherwise 4. has broad application scope in land management of mining area and mine information construction. Compound of remote sensing and DTM can be apply to solve mine survey, monitor of surface and marginal slope and so on.

Using aerial photos and high resolution satellite images of the year of 2.04.this paper establishes remote {3. interpretation marks of the Great Wall of Ming Dynasty's damaged levels. Based on field survey and remote {3. survey in 1984.we analyzed present situation and changing characteristics being of the Great Wall of Ming Dynasty in beijing. The results show that about 7.02. of the wall is well-preserved (about 2.861 m); 3..5% of the wall is slightly or moderately dam-aged (about 115989 m); 61.5% of the wall is badly damaged (about 2.63.9 m). This paper analyzes the dynamic change of the Great Wall of Ming Dynasty. It shows that the damaged situation of the Great Wall of Ming Dynasty in beijing is serious. From 1984.to 2.04.the well-preserved wall is decreased by 3.2.6 m (decreased by 56%); badly damaged wall increased by 512.7 m (increased by 67%). Finally,this paper analyzes the influence factors of damaging Great Wall. The conclusion is as follows: The damaged Great Wall is generally near the roads and villages,small slope,and easily arriving land.

A LAI Inversion Algorithm Based on Directional Reflectance

Chapter 12.Numerical Inversion Methods in Geoscience and Quantitative remote sensing

＜正＞Leaf area index (LAD is an important ecological and environmental parameter. The current remote sensing inversion methods of leaf area index can mainly（?）e grouped into two classes: vegetation index based methods and remote sensing physical model based methods. In this paper, a new LAI retrieval method is developed. The algorithm borrows ideas from the principles and methods of ground LAI measurements, and adopts a new frame which differs from traditional remote sensing LAI inversion methods. First, the relationship between LAI and directional gap fraction is derived from the definition of LAI. Then, directional gap fraction is acquired from remote sensing bidirectional reflectance distribution function （BRDF） product. This acquisition is obtained by the use of a kernel driven model and a large scale directional gap fraction algorithm. At last, the large scale LAI is calculated through angle integrations. This algorithm has been applied to get LAI distribution of China in the middle of July, 2.02. The ground data acquired from two field experiments conducted in Changbai Mountain and Qiiian Mountain, China, are used to validate the algorithm. In order to resolve the scale change problem between high resolution grouad observation and low resolution remote sensing data, two high resolution remote sensing images almost ha, ing the same resolutions with ground measurements are used as transitions. In order to proceed, we first bulid an empirical relationship between measured LAI and high resolution reflectance. Then, we get high resolu ion LAI distribution according to that relation. The LAI value of a low resolution pixel is calculated from the areal weighted sum of high resolution LAIs composing the low resolution pixel. Our results show that the algo（?）ithm has a high precision. Factors that may influence the precision of the algorithm are also discussed in this paper.
