Dear Laura,<br /><br />I read the comments carefully and address all of them. Based on your suggestions, I have made some revisions and modify the title as &ldquo;Effects of green spaces on expanding urban heat island in mega-city: mitigation and diversification&rdquo;.<br /><br />I really appreciate for your professional and accurate comments which make my manuscript more readable and fluency. Attached please find my revision and give it a second look. I'm looking forward to&nbsp;your more suggestions. Thanks for your help!<br /><br />Best regards,<br /><br />Sun<br /><br />rhsun@rcees.ac.cn
