高速交通正在取代传统交通,传统交通的命运面临着挑战。速度世界正在呈现多样性分异特征,可以为传统交通找到适合的生存空间。基于旅游的视角,对类似贝加尔湖这样的大资源区不仅可以有利于传统交通继续发挥作用,而且还可以保护交通遗产... 高速交通正在取代传统交通,传统交通的命运面临着挑战。速度世界正在呈现多样性分异特征,可以为传统交通找到适合的生存空间。基于旅游的视角,对类似贝加尔湖这样的大资源区不仅可以有利于传统交通继续发挥作用,而且还可以保护交通遗产,更进一步促进观光旅游的发展。大资源区旅游化与遗产化是两个重要概念,基于这两个概念可以提出传统交通的新型旅游生存模式,延伸出慢速稀缺、条件化合、文化捡拾等观点。 展开更多

Since 1790, Antarctic living resources were becoming subjects of competition among the exploiters to be first in obtaining the maximum profit from them. This led to subsequent extinction of valuable species from fur seals and next penguins, large through small whales, industrial demersal fish, further to pelagic species and now toothfish, crabs and krill. Catch proportions of their numerous and biomass decrease. The biomass of South Georgia Icefish estimated for 40 years in spide of decreasing trend has one of the largest components-the oscillations with periods of 3 years or 4 years. Their models explain large biomass fluctuations in the years 1975 to 1981 with amplitudes ±15 × 10^3 tonnes around average 20 ×10^3 tonnes and further decline up to 2005 season with oscillation ±4 ×10^3 tonnes around average 5 × 10^3 tonnes. For future season, 2016 model predicts a little increase of the biomass oscillation at level of 8 × 10^3 tonnes with reduced amplitude 2 × 10^3 tonnes. Slowly increase density of adult fish was also reported for target similar and close related mackerel icefish. Additional references for biomass levels help reduce the risk of further depletion biomass of Pseudochaenichthys georgianus which already declined to 75%. As global warming promote phytoplankton growth, replacing krill fishery by algae farms can save unique Antarctic heritages. 展开更多
