A preliminary study on the differentiation mechanisms of soil salinity and plant community of microtopography

Distribution of soil salinity and plant community and their interrelation in several types of microtopography in coast zone were studied. The results show that the microtopography is the key factor affecting the distribution of soil salt. Rainwater accumulation caused by microtopography can effectively desalinize soil. Conducting eco-engineering such as creating microtopography for rainwater accumulation is an effective way for soil amelioration and vegetation construction.
