土地利用格局变化及未来发展情景对省域土地合理规划和生物多样性保护具有重要意义。以东部典型区域浙江省为例,根据浙江省2013和2018年两期精度500 m×500 m土地利用数据、浙江省陆地国家公园、国家级自然保护区数据,分别设置了土... 土地利用格局变化及未来发展情景对省域土地合理规划和生物多样性保护具有重要意义。以东部典型区域浙江省为例,根据浙江省2013和2018年两期精度500 m×500 m土地利用数据、浙江省陆地国家公园、国家级自然保护区数据,分别设置了土地利用结构和经济社会发展速率维持现状的情景、自然保护地体系建立情景和城市扩张情景。选取高程、坡度、人口等11种影响因素作为驱动因子,采用CLUE-S模型拟合浙江省2018年的土地利用覆被格局并判断拟合精度,进而模拟出三种情景下研究区2030年的土地利用格局演变。结果表明:1)Logistic二元回归分析结果ROC值均大于0.699,表明所选驱动因子对土地利用类型的解释能力较为准确。2)Kappa系数高达0.9460,表明模型能够准确的模拟浙江省土地利用分布格局;3)与2018年浙江省土地利用情况相比,2030年在不同情景下土地利用面积与空间分布均发生了一定的变化,土地利用结构和经济社会发展维持现状情景下建设用地持续扩张,建设用地面积增加16575 hm^(2),显著增加的区域主要位于杭州市郊和温州市郊。自然保护地体系建立情景下,林地、水域分别增加了15625、1600 hm^(2),耕地、草地和建设用地分别减少了1550、1700和13975 hm^(2),空间上都呈现均匀变化。城市扩张情景下,建设用地面积迅速增加145800 hm^(2),增加部分多数位于原有建设用地的外围。三种情景对比下,自然保护地体系建立情景是浙江省2030年最适宜的土地利用土地覆被格局。2030年浙江省在自然保护地体系建立情景下生态空间的面积最大,为6741925 hm^(2),年均增加速度为0.0192%。 展开更多

Graphite is a rare and important nonmetallic mineral. Till 2017, the global graphite resource reserves had exceeded one billion tons, which are mainly distributed in China (0.45 billion tons), Mozambique (0.14 billion tons), Madagascar (0.1 billion tons), Turkey (0.09 billion tons), Brazil (0.07 billion tons), and Tanzania (0.07 billion tons). These six countries include about 92% of the global graphite resource reserves, of which China accounts for about 45% of the world's total resource reserves. 展开更多

This thesis carefully appreciated situational irony in some of Shakespeare's tragedies successively,and classified situational irony into four kinds:discrepancy between appearance and reality,expectation and fulfilment,intention and outcome,the actual circumstances and appropriateness.In the analysis of the first kind of situational irony,especially,the thesis focused on Antony and Cleopatra,together with Julius Caesar,questioned the common idea,and stated that Antony's failure was not because of his passion towards Cleopatra.Cleopatra was only his screen to cheat the world,an excuse of his " face-saving failure". 展开更多

There are some positive changes on the two sides of the Korean Peninsula in 2018;the situation on the peninsula has released a signal of relaxation;it seems that the Korean Peninsula presents the “double suspension” situation which has been advocated by the Chinese government, and both the two sides of the Korean Peninsula have shown a strong will to ease the tension on the peninsula, and promote the inter-Korean relations to ease and improve the bilateral relations. As a close neighbor of the Korean Peninsula, in the face of the current situation on the peninsula, China should focus on deepening cooperation between China and the United States on the Korean nuclear issue, institutionalize the development of inter-Korean relations, and enhance its capability to resolve the Korean nuclear issue peacefully. 展开更多
