海岸带土壤理化性质与地下水位对植树造林的影响分析——以东营和连云港地区为例

Effects of Soil Physicochemical Properties and Groundwater Level on Afforestation in Coastland——A Case Study of Dongying and Lianyungang

对山东东营市河口区新户乡所在的渤海海岸带和江苏连云港市徐圩盐场所在的黄海海岸带土壤质地、pH值、含盐量、有机质含量等理化性质指标以及地下水位和矿化度进行调查、测定与对比分析,并根据土壤理化性质和地下水的测定结果以及植物的耐盐性和对水湿状况适应性能,在连云港徐圩盐场的不同地段,选择不同的树种进行造林实验。结果表明,山东东营地区选择的冬枣树种对该地的气候、土壤、地下水比较适应,造林取得了良好经济效益和生态效益;连云港徐圩盐场各地段所选择的冬枣、紫穗槐、杨树、苦楝、栾树、青檀、杜仲、国槐、刺槐、旱柳、合欢、银杏等树种对当地局地环境也较为适应,总体造林效果基本达到设计要求,但在局部地段的苗木选择、植树方法等方面值得进一步探讨。

The soil texture, pH, salinity, organic matter, groundwater level and mineralization degree in Bohai sea coastland in Xinhu village, Dongying city, Shandong province and in Yellow sea coastland in Xuwei salt field, Lianyungang city, Jiangsu province are investigated, measured and analyzed. According to soil physicochemical properties, groundwater lever, and the ability to endure salinity and humidity, different species of seedling to plant in different area in Xuwei salt field is chosen. The result shows that Ziziphus jujuba is more fit to climate, soil and groundwater level in Bohai sea coastland and gain good economic and ecological benefit; Ziziphus jujuba,Amorpha fruticosa,Populus L.,Melia azedarach,Koelreuteria paniculata,Pteroceltis tatarinowii,Eucommia ulmoides,Sophora japonica,Robinia pseudoacacia,Salix matsudana,Albizia julibrissin,Ginkgo biloba are fit to conditions of Xuwei salt field and gain the basic afforestation benefit, but the chosen species of seeding and tree planting technique should be further researched in some area of the salt field.
