摘要
[目的]探索东营滨海盐碱地造林技术，对滨海盐碱地生态造林模型进行研究。[方法]共设计5个造林模型，于2010～2013年在东营市河口区、垦利县和利津县进行分年度造林，造林结束后，按造林模型、造林年度，分乡镇对幼林进行全面调查。[结果]5个造林模型下幼林质量达一类林要求比例均高于90．0％（除2013年垦利试验点发生涝灾以外），其中，模型1一类林比例达100％，模型4较低，也达94．0％以上；分乡镇统计结果显示，河口区各乡镇造林幼林一类林达标率达100％，利津县最低，各乡镇造林幼林一类林平均达标率为92．9％；分年度统计结果显示，一类林达标率均高于90．0％，2013年由于发生洪涝灾害，一类林达标率最低，为93．9％。[结论]5个造林模型均适用于东营滨海盐碱地造林。
Abstract
Objective] To explore the afforestation technology in coastal saline soil in Dongying City, and to research the ecological afforestation model in coastal saline soil.[Method] A total of five afforestation models were designed.Afforestation in Lijin County, Kenli County, Hekou District of Dongying City was carried out in each year from 2010 to 2013 (except the waterlog in test site of Kenli County in 2013).[Result]Pro-portion of first-class forest of model 1 reached 100%, but model 4 was relatively low, reaching more than 94.0%.Statistics results showed that the standard reaching rate of first-class forest in Hekou Area reached 100%, while that in Lijin County was the lowest.The average standard reaching rate of first-class forest in each townships was 92.9%.Annual statistics showed that the standard reaching rates of first-class forest were wall higher than 90.0%.Due to the flood disaster in 2013, the standard reaching rate of first-class forest was the lowest, which was 93.9%. [ Conclusion] The five afforestation models are suitable for the afforestation in coastal saline soil of Dongying City.
