The invention relates to a degraded
wetland vegetation in-situ
recovery method, which is characterized in that according to the method, a seed
bank resource remained in selected degraded
wetland soil is utilized for carrying out
vegetation in-situ
recovery. The method comprises the following steps that 1) a
soil seed bank is surveyed, and whether the degraded
wetland has the
vegetation in-situ
recovery conditions or not and the
plant types with the advantages in the
soil seed bank are determined; 2) the water supplementation is carried out on regions meeting the vegetation in-situ recovery conditions in the first step, and in addition, the ground
surface water level and the
soil moisture content are controlled; 3) the ground surface vegetation after the degraded
wetland vegetation in-situ recovery in the second step is surveyed; and 4) the successfully recovered
soil seed bank is surveyed to confirm the recovery completion. The method has the advantages that the self remained soil seed
bank resource is sufficiently utilized, the operation is easy, the maintenance cost is low, the vegetation recovery is fast, the
species diversity is high, and the popularization and the application are easy.
