Hello! I need to impoverish these two teams and there must be 2 colorbar, how do I do this ???
x=[1:150]
y=[1:150]
z=rand(1,150) % summer
p=rand(1,150) % winter
figure(1)
imagesc(x,y ,p)
colormap(winter)
colorbar;
hold on
scatter( x,y,[],z,'d', 'filled')
colormap(summer)
colorbar;
hold off

What do you mean by "impoverish"? To me it means to make poorer, less wealthy, have less money, none of which seem to apply to images and scatterplots. For what it's worth, I'm attaching demos for how you can combine multiple plots or images onto a single axes.

Assuming you want to display one scatter plot over one imagesc graph both having different colormap and colorbar. Give the below code a try.
close all; clc;
x = 1:150;
y = 1:150;
z = rand(1, 150);
p = rand(1, 150);
figure; ax1 = axes;
% Plot first data
imagesc(ax1, x, y ,p);
hold on;
% Plot second data
ax2 = axes;
ax2.YDir = 'reverse';
scatter(ax2, x, y, [], z, 'd', 'filled');
% Hide the top axes
ax2.Visible = 'off';
ax2.XTick = [];
ax2.YTick = [];
% ax2.YDir = 'reverse';
% Add differenct colormap to different data if you wish
colormap(ax1, 'winter')
colormap(ax2, 'summer')
% Set the axes and colorbar position
set([ax1,ax2],'Position', [.17 .11 .685 .815]);
cb1 = colorbar(ax1,'Position', [.05 .11 .0675 .815]);
cb2 = colorbar(ax2,'Position', [.88 .11 .0675 .815]);
hold off;
