绘制海岸线国界州界及填充海陆

1. 海岸线 Basemap.drawcoaslines()

( V) I* i5 O) M0 ?# f

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

#87CEEB

" r$ C. E$ ^ l7 e: F! T

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

陆地为橄榄色

3 c! m: ^# S4 C/ D6 U( f4 h# v) Z

#808000

湖泊为天蓝色

#87CEEB
