Zen has become especially popular after 1950 and the Zen craze of East Asia not only has become a kind of belief but also a way of life in America. Many American writers introduce, advocate, and concentrate on their Zen, and even go to the East to learn Zen. They applied the ideology, content and allusions of Chinese Zen to their works, so they have a close relationship with Chinese Zen. This article aims to analyze the poems of Kenneth Rexroth, Anthony Piccione, Gary Snyder and James P. Lenfesty to explore the mysterious relationship between Chinese and American poetry. These poets imitate the quiet beauty, wild freedom or orthodox of Zen poetry. Furthermore, each of them forms their own writing characteristics, thus creating a new realm of American poetry.

International audience ; Land cover changes, especially excessive economic forest plantations, have significantly threatened the ecological security of West Dongting Lake wetland in China. This work aimed to investigate the spatiotemporal dynamics of forests in the West Dongting Lake region from 2000 to 2018 using a reconstructed monthly Landsat NDVI time series. The multi-type forest changes, including conversion from forest to another land cover category, conversion from another land cover category to forest, and conversion from forest to forest (such as flooding and replantation post-deforestation), and land cover categories before and after change were effectively detected by integrating Breaks For Additive Seasonal and Trend (BFAST) and random forest algorithms with the monthly NDVI time series, with an overall accuracy of 87.8%. On the basis of focusing on all the forest regions extracted through creating a forest mask for each image in time series and merging these to produce an 'anytime' forest mask, the spatiotemporal dynamics of forest were analyzed on the basis of the acquired information of multi-type forest changes and classification. The forests are principally distributed in the core zone of West Donting Lake surrounding the water body and the southwestern mountains. The forest changes in the core zone and low elevation region are prevalent and frequent. The variation of forest areas in West Dongting Lake experienced three steps: rapid expansion of forest plantation from 2000 to 2005, relatively steady from 2006 to 2011, and continuous decline since 2011, mainly caused by anthropogenic factors, such as government policies and economic profits. This study demonstrated the applicability of the integrated BFAST method to detect multi-type forest changes by using dense Landsat time series in the subtropical wetland ecosystem with low data availability.
