In this paper, based on the healthy development of ecological environment in the Loess Plateau area , proposed 18 indices of ecological environment quality evaluation, established index system of ecological environment quality evaluation and fuzzy comprehensive evaluation model. Taking Jiuyuangou basin as example, made a conclusion that Jiuyuangou ecological quality of the environment is under Ⅱ, fragile ecological environment quality for the general area, it is because of measures implementation of the Soil and Water Conservation Demonstration Area to increase the vegetation cover, soil erosion control, and promote the improvement of ecological environment.

The application of deep learning (DL) in various brain computer interface (BCI) systems has achieved great success, but the results on the attention classification task are still not satisfactory. In this paper, an end-to-end mixed neural network model was proposed to classify the attention and nonattention mental states from multi-channel electroencephalography (EEG) data. During the experiment, a cross-subject strategy was performed on the attention detection task. Evaluated on a different electrodes combination of a publicly available dataset, the proposed model outperforms these baseline methods while maintaining relatively low computational complexity. The improved performance is meaningful for the attentive mental state classification task and is useful for the process of attention enhancement.

This paper presents a kind of two-input Cellular Neural Network (CNN). This kind of CNN has three templates: A-template, B-template and C-template. The B-template and C-template are in charge of coupling two input images to be processed by the CNN equation. It is expected the new CNN may be used to process simultaneously two images. As an application of the CNN, a background replacement (BR) CNN is introduced. The BR CNN can replace the light colored background of a RBG image by another color image. Two computer simulation examples show that the BR CNN image processing can display animated drawing effects, and animated cartoons.
