研究区位于盐城市灌东地区滨海盐碱地。通过采用客土掺拌、施加有机肥、喷洒硫磺与添加土壤改良剂、淡水洗盐、挖沟起垄等措施对盐碱地进行改良，使土壤含盐量下降至正常范围。在此基础上，遵循因地制宜、适地适树的原则，合理栽植柽柳、女贞、臭椿等耐盐碱树种，采用株间混交、块状混交等混交模式，提高造林成活率，达到改善生态环境的目的。
The research area is located in the coastal saline-alkali land in Guandong Area of Yancheng city. The salt and alkali soil was improved by mixing with passenger soil, applying organic fertilizer, spraying sulfur and adding soil conditioner, washing salt with fresh water, digging trenches and ridging, etc., on this basis, following the principle of adapting measures to local conditions, planting salt-resistant trees such as Tamarix chinensis, Ligustrum chinensis and so on, adopting mixed planting modes such as inter-plant mixed planting and block mixed planting, improving the survival rate of afforestation and improving the ecological environment.
