Application of Regional Characteristic Elements in Designing of Kindergarten Environmental Landscapes

Presently, there are many problems on kindergarten designing. For example, visual perception is always the priority for outdoor landscapes, and sandpit and children＇s slide are always devices for attracting children. The research analyzed the role of regional characteristics in designing kindergarten landscapes and proposed that the regional elements should be taken into consideration, providing references for characteristic designs of kindergarten landscape.

Formation and syn-rifting process of the Wan'an Basin, South China Sea

Based on seismic and drilling data, we calculated tectonic subsidence amounts and rates of the Wan'an Basin by backstripping. The genetic mechanism and syn-rifting process of the basin were analyzed in combination with the regional geological setting. The results reveal that the basin syn-rifted in the Eocene and early Miocene under the control of the dextral strike-slip Wan'an Fault Zone. The transtensional/ extentional stresses along this fault zone may be attributed to seafloor spreading of the South China Sea (SCS) in multiple episodes. Extensive basal faults and some small initial rifts in the early Paleogene can be related to southeastward extrusion and clockwise rotation of the Indochina Block. During the Oligocene, the nearly N-S directed spreading of the SCS derived the transtensional stresses in a roughly NW-SE orientation. The basin subsided rapidly in the middle and north to form two major subsidence centers. In the early Miocene, the SCS spread again in a nearly NW-SE direction, resulting in rapid subsidence in the southern basin continuous extending until the period ～16.3 Ma.

Tectonic Background of the Yutian M_S7.3 Earthquake in 2014 and Its Relationship with the Yutian M_S7.3 Earthquake in 2008

The regional tectonic background and characteristics of active faults of the Yutian MS7.3earthquake on February 12,2014 are discussed in this paper.After the analysis of the epicenter area of the MS7.3 earthquake in 2014 and the focal mechanisms of the former strong earthquakes around it,the authors deduced that the seismogenic fault of the MS7.3earthquake is the east branch of the Ashikule fault.The MS7.3 earthquake in 2014 and the MS7.3 earthquake in 2008 are two strong earthquake events on the different sections of the Altun Tagh fault,where the fault behavior changes from sinistral slip to normal faulting because of the extensional tail effects in the southern end of the Altun Tagh fault.It is concluded that the two MS7.3 earthquakes have the same dynamic source,and the MS7.3earthquake in 2008 promoted the occurrence of the MS7.3 earthquake in 2014.Finally,we calculate the Coulomb stress change to the seismogenic fault of the MS7.3 earthquake in2014 from the MS7.3 earthquake in 2008 using the layered crust model.The result also shows that the MS7.3 earthquake in 2008 accelerated the occurrence of the MS7.3earthquake in 2014.

论田园景观在现代景观中的回归和运用

随着城市的扩展、人口的激增以及生存环境的进一步恶化,人类开始自我反省并呼唤爱护自然,保护生态平衡,从大自然中找回生存价值和希望。这种人类共同的心声通过生态环境景观的形象表现得到了充分的体现。近几年,环境景观设计风格的主流开始从过去一味追求档次,追求华丽的风格转向简约。

How Snow Leopards Share the Same Landscape with Tibetan Agro-pastoral Communities in the Chinese Himalayas

The snow leopard(Panthera uncia)inhabits a human-altered alpine landscape and is often tolerated by residents in regions where the dominant religion is Tibetan Buddhism,including in Qomolangma NNR on the northern side of the Chinese Himalayas.Despite these positive attitudes,many decades of rapid economic development and population growth can cause increasing disturbance to the snow leopards,altering their habitat use patterns and ultimately impacting their conservation.We adopted a dynamic landscape ecology perspective and used multiscale technique and occupancy model to better understand snow leopard habitat use and coexistence with humans in an 825 km^(2) communal landscape.We ranked eight hypothetical models containing potential natural and anthropogenic drivers of habitat use and compared them between summer and winter seasons within a year.HABITAT was the optimal model in winter,whereas ANTHROPOGENIC INFLUENCE was the top ranking in summer(AICc_(w)≤2).Overall,model performance was better in the winter than in the summer,suggesting that perhaps some latent summer covariates were not measured.Among the individual variables,terrain ruggedness strongly affected snow leopard habitat use in the winter,but not in the summer.Univariate modeling suggested snow leopards prefer to use rugged land in winter with a broad scale(4000 m focal radius)but with a lesser scale in summer(30 m);Snow leopards preferred habitat with a slope of 22°at a scale of 1000 m throughout both seasons,which is possibly correlated with prey occurrence.Furthermore,all covariates mentioned above showed inextricable ties with human activities(presence of settlements and grazing intensity).Our findings show that multiple sources of anthropogenic activity have complex connections with snow leopard habitat use,even under low human density when anthropogenic activities are sparsely distributed across a vast landscape.This study is also valuable for habitat use research in the future,especially regarding covariate selection for finite sample sizes in inaccessible terrain.
