The article is studying on the Haikou city, using Remote Sensing technique and GIS technology, with ArcGIS, ERDAS, FRAGSTAS, analyzing the temporal and spatial variation of landscape in Haikou City from 2000 to 2010, drawing the conclusion: residents, construction, farmland and forest land is the main part of landscape pattern and increased rapidly. Besides the decrease of unused land and water area, it also reflects that not only the landscape fragmentation degree of the integral sight in Haikou City in relatively high, but the landscape fragmentation degree of the residents, construction, farmland and forest land, which are the main part of Haikou City , is also relatively high.. Besides, the data also shows that each landscape didn’t connect well and the exchange of material energy among landscapes is not smoothly, which go against the mutual development between the landscape. However, the distribution of landscape in Haikou City is fairly balanced. There is no particularly advantaged type, which contributes to the balanced development of the landscape.

Fragmentation Degree

Numerous resource allocating and releasing will cause fragmentation which will seriously affect the I/O performance of file systems. One method to solve this problem is file defragmentation. This paper focuses on fragmentation detection, the key part of the file defragmentation. We estimate file fragmentation situation through file’s layout, and then analyze the detailed effects of the situation on performance measurement. Then we quantize this by the file’s “fragmentation degree” through theoretical and experimental analyses. Finally we use it to estimate the file’s fragmentation and decide whether the file needs to be defragmented.

Theoretical exploration of network structure significance requires a range of different networks for comparison. Here, we present a new method to construct networks in a spatial setting that uses spectral methods in combination with a probability distribution function. Nearly all previous algorithms for network construction have assumed randomized distribution of links or a distribution dependent on the degree of the nodes. We relax those assumptions. Our algorithm is capable of creating spectral networks along a gradient from random to highly clustered or diverse networks. Number of nodes and link density are specified from start and the structure is tuned by three parameters (γ, σ, κ). The structure is measured by fragmentation, degree assortativity, clustering and group betweenness of the networks. The parameter γ regulates the aggregation in the spatial node pattern and σ and κ regulates the probability of link forming.

In order to obtain the relationship between fractal dimension and energy dissipation of rock-like materials under initial stress state, a variable cross-section split Hopkinson pressure bar (SHPB) test system with active confining pressure loading device was used to carry out impact compression and splitting tests on cemented sand specimens. The impact test results show that (1) the prediction value on the fragmentation degree of cemented sand specimens by using the fractal model is basically consistent with the screening results of actual test, which verifies the applicability of the fractal calculation model given in this study; (2) the more the fracture energy dissipated in the crushing process of cemented sand specimens, the more serious the fragmentation degree is, and accordingly the larger the fractal dimension is, that is, the fracture energy is positively correlated with the fractal dimension; (3) there is an exponential relationship between the fractal dimension and energy dissipation of cemented sand specimens under initial stress, which is so different from that under no initial stress. The experimental results in this study can be used to modify the fractal damage model for rock blasting considering the initial stress.

In order to find the distribution law of coal fragmentation, mathematic model of size distribution was built according to fractal theory. Based on this, the experiments of impactive crash were carried out under different impact rate and different Protodikonov's hardness. The comparison between Weibull distribution and fractal distribution was done so as to find the relationship between the influence parameters and the coal fragmentation characteristic index, the coal fragmentation degree coefficient and the fractal dimension. The results indicate that both two types of distribution functions are suitable for the distribution discipline of coal fragmentation, but the relationship of the coal fragmentation degree and impact parameter is not reacted correctly by the coal fragmentation characteristic index and coal fragmentation degree coefficient in the Weibull distribution while the coal fragmentation degree could be expressed by the fractal dimension in fractal distribution. The relationships between the fractal dimension and the rate, the Protodikonov's hardness of coal are linear.

The myofibrillar fragmentation degree (MFI), value of pH and the degradation degree of sea bass with high pressure treatment were studied. The results showed that the degradation degree of protein, MFI and pH of sea bass increased as the pressure increasing, indicating that ultra high pressure treatment could change the tenderness of sea bass muscle, which has a certain practical significance in the food industry.
