cartopy stock_img

`cartopy` 是一个 Python 库，用于绘制地图和地理数据。`stock_img` 是 `cartopy` 中的一个模块，用于获取常用的地图背景图像。可以使用以下代码导入 `cartopy` 和 `stock_img` 模块：

import cartopy.crs as ccrs
import cartopy.feature as cfeature
from cartopy.io import shapereader
import matplotlib.pyplot as plt

# 获取地图背景图像
land = cfeature.NaturalEarthFeature('physical', 'land', '110m',
                                    edgecolor='face',
                                    facecolor=cfeature.COLORS['land'])
ocean = cfeature.NaturalEarthFeature('physical', 'ocean', '110m',
                                     edgecolor='face',
                                     facecolor=cfeature.COLORS['water'])
lakes = cfeature.NaturalEarthFeature('physical', 'lakes', '110m',
                                     edgecolor='face',
                                     facecolor=cfeature.COLORS['water'])
rivers = cfeature.NaturalEarthFeature('physical', 'rivers_lake_centerlines', '110m',
                                      edgecolor=cfeature.COLORS['water'],
                                      facecolor='none')

# 绘制地图
fig = plt.figure(figsize=[10, 5])
ax = fig.add_subplot(1, 1, 1, projection=ccrs.PlateCarree())
ax.set_extent([73, 135, 18, 53], crs=ccrs.PlateCarree())
ax.add_feature(land, facecolor='gray')
ax.add_feature(ocean)
ax.add_feature(lakes)
ax.add_feature(rivers)
plt.show()

这段代码将绘制一个包含陆地、海洋、湖泊和河流的地图。你可以根据需要自定义地图背景。
