可以通过调整 subplot 之间的间距来实现四图之间的间隙变小，可以使用 `subplot_tight` 函数来实现。

可以将原来的代码改成以下形式：

figure;
subplot_tight(2, 2, 1, [0.05, 0.05]);
m_contourf(lon_real,lat_real,spring_mean');
colormap(m_colmap('jet','step',100)); 
m_gshhs('fc','patch',[0.8 0.8 0.8]); 
m_grid('box','fancy','fontsize',12); 
h=colorbar('eastoutside'); 
title('春季','fontsize',12); 
title(h,'°C','color','k');

subplot_tight(2, 2, 2, [0.05, 0.05]);
m_contourf(lon_real,lat_real,summer_mean');
colormap(m_colmap('jet','step',100)); 
m_gshhs('fc','patch',[0.8 0.8 0.8]); 
m_grid('box','fancy','fontsize',12); 
h=colorbar('eastoutside'); 
title('夏季','fontsize',12); 
title(h,'°C','color','k');

subplot_tight(2, 2, 3, [0.05, 0.05]);
m_contourf(lon_real,lat_real,autumn_mean');
colormap(m_colmap('jet','step',100)); 
m_gshhs('fc','patch',[0.8 0.8 0.8]); 
m_grid('box','fancy','fontsize',12); 
h=colorbar('eastoutside'); 
title('秋季','fontsize',12); 
title(h,'°C','color','k');

subplot_tight(2, 2, 4, [0.05, 0.05]);
m_contourf(lon_real,lat_real,winter_mean');
colormap(m_colmap('jet','step',100)); 
m_gshhs('fc','patch',[0.8 0.8 0.8]); 
m_grid('box','fancy','fontsize',12); 
h=colorbar('eastoutside'); 
title('冬季','fontsize',12); 
title(h,'°C','color','k');

其中，`subplot_tight` 的第四个参数是一个长度为2的向量，用来设置左右和上下的间距。可以根据需要进行调整。
