分步排查，看哪步最慢，再分别优化吧.

[解决办法]
看了一下，没有什么明显要改的……
随便说点：
1.单条语句尽量写简短点(配合临时表等)
2.in,not,exists都导致无法有效利用索引，可适当寻求替代方案。
比如：DELETE FROM Gps_PE_PT_ReflowZones WHERE UID IN(SELECT tmpUID FROM #tmptb)
可写成：
DELETE Gps_PE_PT_ReflowZones
FROM #tmptb t
WHERE Gps_PE_PT_ReflowZones.UID=t.tmpUID

感觉楼主的嵌套太多了。
如果确实有必要，那另当别论，否则，尽量不要那么多嵌套，影响效率。

还有一个not,exists 这些地方，确实无法利用索引。

最主要的是要一块块的调试。一起调试总归看不出问题来。

分步查一下，再用执行计划看看
如果不是需要，嵌套不要太多
