A 3（syntax）×2（semantic relation） factorial design is adopted, with syntax and semantic relations as within-participant variables. The experiment finds that the semantic mismatch is most likely to increase cognitive loads as people have to spend more time, including first-pass time, regression path duration, and total fixation duration. Double negation does not significantly increase the processing difficulty of pictures and information. Experimental results show that people can extract the special syntactic strategy from long-term memory to process pictures and sentences with different semantic relations. It enables readers to comprehend double negation as affirmation. These results demonstrate that the constituent comparison model may not be a general model regarding other languages.展开更多

[Method] With the documents of 1：10 000 topographic maps, updated Forest Resource Inventory Data, based on the GIS platform and Fragstats software, the paper analyzed the patterns and heterogeneity of forest landscapes by adopting the landscape ecological theory and the method of landscape index. [Result] The forest landscape types, in terms of area occupation from large to small, are in the order of evergreen broad-leaved forest, coniferous mixed forest, evergreen and deciduous broad-leaved mixed forest, shrubs, mixed needle leaf forest, suitable land for forest deciduous broad-leaved forest and non-forest. [Conclusion] Overall, the Reserve had maintained sufficient forest landscape diversity with a low level fragmentation. The distribution of various types of forest landscape was extremely uneven, dominated by several types such as evergreen broad-leaved forest, coniferous forest, etc.展开更多

The results showed that the overall forest landscape in Maolan Nature Reserve was quite good, but with the increasing natural interferences and human activities, shrub forests and non-woodland landscape types have been multiplied; among the 3 functional zones of the Nature Reserve, landscape fragmentation degree is low in core zone and buffer zone, but high in experimental zone.展开更多

But the landscape on the way was extraordinary： yellow rape blossoms flourished along roads; the plateau grassland was dotted with many anonymous flowers -- red, purple or yellow; high mountains were permeated by clouds and mists, springs and streams ran down from top of mountains; and goats and yaks grazed leisurelv on mountain slopes in the distance. All those testified to the truth of a popular proverb -- ＂Beautiful landscape is always on the way＂.展开更多
