In order to overcome the problems of poor denoising effect, large quantitative accuracy error and large spatial accuracy error of current land use change simulation methods, a dynamic simulation method of land use change based on geographically weighted CLUE-S model was proposed. Using CLUE-S model to simulate the expansion of urban space, combined with geographic weighted logistic stepwise regression method, the influencing factors of land use change were analysed. The spatial distribution of future land use area is realised by iteration, and the spatial visualisation simulation of land use prediction is realised. The experimental results show that the signal-to-noise ratio of the proposed method is more than 85 dB, the quantitative and spatial accuracy errors are less than 4%, and the ROC value is close to 1, which proves that the spatial simulation effect is relatively good.

In order to overcome the low efficiency of feature extraction in traditional research methods for spatial distribution of urban landscape pattern, a new research method based on multi-source remote sensing technology is proposed. Combined with the idea of information entropy and grid division, the spatial secondary grid division of urban landscape pattern is completed by multi-source remote sensing technology. The probability density of spatial distribution of urban landscape pattern is calculated according to the results of secondary grid division. The scale pyramid is established to study the spatial distribution characteristics of urban landscape pattern. The experimental results show that the proposed method can effectively realise the research of spatial distribution characteristics of urban landscape pattern, with high efficiency of feature extraction, and the maximum extraction time is only 0.22 min.

In order to overcome the problems of large image deviation and unsatisfactory details retention in traditional monitoring methods, a new remote sensing dynamic monitoring research of land cover in ecological protection area based on GIS technology was proposed. In this method, the combination of joint entropy and optimal index is used to analyse and collect remote sensing images. The geometric distortion is corrected by using the binary homogeneous polynomial correction transformation formula. According to the image enhancement, the invalid information of the image is removed, and the land cover type change is described. Finally, the prediction of land cover dynamic change in the future is completed by creating Markov model. The experimental results show that the accuracy of the land cover remote sensing image data obtained is high, the land cover monitoring rate is 73%, the pixel accuracy is more than 90%, and the edge information maintenance advantage is significant.

In order to overcome the problem that the urban green landscape pattern construction effect is not ideal, this paper proposes the research method of spatio-temporal evolution of urban complex landscape pattern based on remote sensing technology. This method collects landscape pattern information. Landscape images are processed by radiometric correction and geometric correction, and spatial pattern indices are calculated. The experimental results show that: under the research method of spatiotemporal evolution of landscape pattern in this paper, the landscape area of dry land is reduced more, the transfer volume of residential, industrial and mining land and water area is less, and the stability is stronger. The density of landscape edge increased, indicating that the degree of landscape fragmentation in the city has a deepening trend. In terms of landscape spatial heterogeneity, the overall pattern tends to be coordinated, which indicates that the proposed method has good application performance.

Activated carbon, obtained by phosphoric acid activation of Coffea arabica fruit endocarp, was used to remove 2,4-dichlorophenol from aqueous solutions in a micro-packed bed adsorber. In batch experiments, effects such as initial concentration, solution's pH, and temperature on adsorption were investigated. It was found that acidic pH is favourable and that the adsorption isotherm is best represented by the Langmuir model. In continuous experiments, the effect of inlet concentration, bed length, and flow rate on the adsorption capacity of the micro-packed bed adsorber were evaluated. Adsorption capacities were higher than those obtained in batch experiments. Inlet concentration and bed length show a significant effect on the adsorption capacity. Breakthrough curves were very well fitted by axial dispersion model. Additionally, breakthrough profiles indicate a particle-controlled process, which suggest a negligible external mass transfer resistance.
