绘制海岸线国界州界及填充海陆

1. 海岸线 Basemap.drawcoaslines()

- c9 w3 J# v A; W; p

2. 国界线 Basemap.drawcountries()

. \8 h! \7 u; U% t1 B/ R6 j3 }

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)

) s @+ Q: y5 X4 |3 S1 }/ d

此处海洋颜色的天蓝色

#87CEEB

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

陆地为橄榄色

$ M, U) _3 u* v

#808000

6 q3 n* X9 g" l

湖泊为天蓝色

#87CEEB
