Luozha River is a first branch of Lancang River in its middle section. A less known deciduous monsoon forest was recently discovered on the dry-hot banks of Luozha River. The deciduous monsoon forest is 15-20 m tall with Lannea coromandelica Colona floribunda. Mallotus philippensis as the dominant tree species, and Microstegium ciliatum Eupatorium odoratum、Ageratum conyzoides are the dominant species in the shrub-herb layer.

对罗扎河下游鲜为人知的落叶季雨林进行了群落生态学研究，结果表明：罗扎河下游落叶季雨林群落高度在15~20m之间；群落乔木层以厚皮树、一担柴、粗糠柴、毛果扁担杆、灰毛浆果楝等树种为优势种；灌草层以刚莠竹盖度最大，其余如飞机草、藿香蓟、蹄盖蕨Athyrium sp。
