绘制海岸线国界州界及填充海陆

1. 海岸线 Basemap.drawcoaslines()

* j0 @2 g ~3 q# Z$ ?6 L) }; \! ]

2. 国界线 Basemap.drawcountries()

特别要注意国界线有无争议，此处主要说明basemap画国界线的用法，实际国界线以我们国家（中国）制作的地图为准！

3. 州界线 Basemap.drawstates()，主要针对美洲

4. 用不同颜色填充海洋和陆地

4.1 海洋 Basemap.drawmapboundary(fill_color=#87CEEB)

此处海洋颜色的天蓝色

+ F( E' J0 [- G% _% i

#87CEEB

0 v! F/ b Y) u: {0 b3 V% F

4.2 陆地及湖泊 Basemap.fillcontinents(color=#808000, lake_color=#87CEEB)

$ J: A4 a$ r6 Z- @, J8 R- b( \! ?$ I2 x( x

陆地为橄榄色

#808000

湖泊为天蓝色

#87CEEB
