Published: July 2020

Abstract
The efficiency of the oscillating float-type wave energy devices is closely related to the wave conditions in its working area. Seasonal changes in actual sea conditions are obvious, and they vary greatly throughout the year. Therefore, it is necessary to analyse and predict the wave, and adjust the oscillating float-type wave energy device’s parameters according to the wave conditions to improve the efficiency. Based on the analysis of the long-term wave variation and the short-term stationary characteristics of the wave, the moving regression algorithm is used to predict the wave. Adjust the device parameters according to the wave condition prediction data, and match the wave power and load power to achieve a certain efficiency in the wide power range of the device. The research results can be used for variable load control of wave energy devices.

Authors: Li Zhe 
Published: July 2020

Abstract
The Beijing-Tianjin-Hebei air pollution collaborative governance still has difficulties such as insufficient willingness to participate actively, opportunistic behavior, and lack of stable and coordinated cooperation. By comparing the theoretical implications of collaborative governance and the reality of air pollution control in Beijing, Tianjin, and Hebei, the causes of the dilemma are explained from three levels: relationship networks, action strategies, and governance structures: stress-type relationships between central and local governments, and “strong-Chinese” “Weak” development pattern and asymmetric resource dependence between government and enterprises lead to insufficient participation of local governments and enterprises; it is difficult for the actors to reach consensus on action strategies based on the “benefit-risk” analysis, making it easier for local governments and enterprises Opportunistic behaviors and inability to participate effectively in governance; the “pyramid” governance structure between central and local governments, the governance structure with insufficient communication and coordination between local governments, and the lack of incentives between government and enterprises affect the stability and cooperation of collaborative governance Coordination. In the future, it is necessary to eliminate the predicament of coordinated governance of air pollution in Beijing, Tianjin and Hebei, and promote air pollution through clear division of authority between central and local governments, effective communication and coordination of collaboration groups, improvement of income distribution and risk sharing mechanisms, and construction of selective incentive mechanisms. Effective problem solving.

Authors: Sun Xuan , Lei Ting 
Published: July 2020

Abstract
In this paper, the forest ecosystem classification and risk identification are studied based on statistical learning methods such as cluster analysis and discriminant analysis, taking Daxinganling Forest in Inner Mongolia, Beijing Forest, Jilin Changbai Mountain Forest, Hubei Huitong Forest, Guangdong Heshan Forest, and Linzhi Forest as the research objects. The results show that: (1) The classification of forest ecosystem activity is mainly determined by the forest species. At the same time, the composition and growth of forest species is an important basis for risk classification. (2) Climate factors and soil factors affect forest ecosystem stability and vitality, which is an important basis for testing models after risk identification. Therefore, according to the results obtained in this article, the key to study forest ecology is to plant the most suitable forest species and tree species on various site types and implement corresponding afforestation measures so that the entire region can achieve “suitable trees” and “rational management”, so that the potential of land production can be brought into full play and the goal of “use the land as much as possible” is achieved.

Authors: Wang Y L , Yan J J , Li F , Chen Min , Lü Guonian , Cui Xufeng 
Published: July 2020

Abstract
To explore the overall pollution level of heavy metals in agricultural soil and identify its main pollution sources, the selected eight heavy metals (As, Hg, Cr, Cu, Ni, Pb, Fe, and Cd) in 6 sampling sites of Xinjie Village from Qingjiang River Basin were detected. Nemerow index, Geo-accumulation index and Potential ecological risk index were used to evaluate the soil environmental quality. Results showed that the concentrations of Cd in all 6 sampling sites were relatively higher than the risk screening values for soil contamination of agricultural land. The overall heavy metal pollution level based on Nemerow index was slight. Specifically, the pollution level of Cd was moderate, while other metals were basically at clean level. Results of Geo-accumulation index showed Hg (moderately contaminated to heavily) and Cd (uncontaminated to moderately contaminated) were potential primary pollutants. The comprehensive potential ecological risk based on Potential ecological risk index was moderate, with the potential ecological risk of Cd (considerable) and Hg (moderate) higher than that of other metals. Therefore, the agricultural soil pollution in Xinjie Village was a combined pollution and mainly composed of Cd and Hg. Source analysis showed anthropogenic activities such as industrial and agricultural production were the main contributors to the accumulation of heavy metals in agricultural soil. Cd pollution mainly came from agricultural production (fertilization) and industrial emissions; the pollution source of Hg were mostly industrial emissions and the resulting atmospheric subsidence. Finally, the targeted countermeasures were developed for heavy metal pollution of agricultural soil based on the different pollution source characteristics.

Published: July 2020

Abstract
In order to explore the impact of ecological environmental protection measures on ecological functional zones and promote the sustainable development of ecology, the ecological functional zone of a hilly region in south China is taken as the research object in this study. Combined with the data of ecological environment and land use type in the past ten years, the ecological function index (water conservation index), ecological structure status (forest coverage, grassland coverage, and ratio of wetland in waters), and ecological stress situation (ratio of cultivated land to construction land) are analyzed to reflect the ecological status of ecological functional zones. The results show that in the past ten years, the water conservation index and forest coverage rate in the studied area have been improved significantly, and the ecological condition has become better, which indicates that ecological protection measures such as returning farmland to forest and closing mountains for forest cultivation can improve the ecological environment of ecological functional zones and contribute to the sustainable development of ecology.
