摘要
Salinization of soil is a worldwide problem concerning resources and ecology,especially serious in coastal areas.Testing of 26 sorts of data or parameters are carried out on leaves of 22 plant species(in 24 plant variety) of existing main salt-tolerant plant of the Yellow River Delta region.Data or parameters include the following ele-ments:contents of K+,Na+,Ca2+,Mg2+ and Cl-,contents of protein,fat,total energy,ash and contents of 17 amino acids.The results show that these tested plants have economic values.For example,according to their uses,they can be divided into edible plants,forage plants,medicine or health plants,and some of them can be used for multipurposes.These plants have played important roles in the sustainable utilization of plant resources in coastal areas.This paper has taken evaluations on the economic uses of salt-tolerant plants and given suggestions for saline soil improvement and resource utilization in coastal areas.Based on the results of investigation and experiments,we suppose that the salt-tolerant plants in coastal areas can be grouped into 9 main groups according to their economic value:pioneer plants for saline land improvement,medicine,edible and forage plants,industry material,forestation,breeding material,energy plants and eco-tourism resources.
Salinization of soil is a worldwide problem concerning resources and ecology, especially serious in coastal areas. Testing of 26 sorts of data or parameters are carried out on leaves of 22 plant species （in 24 plant variety） of existing main salt-tolerant plant of the Yellow River Delta region. Data or parameters include the following elements： contents of K^＋, Na^＋, Ca^2＋, Mg^2＋ and Cl^-, contents of protein, fat, total energy, ash and contents of 17 amino acids. The results show that these tested plants have economic values. For example, according to their uses, they can be divided into edible plants, forage plants, medicine or health plants, and some of them can be used for multipurposes. These plants have played important roles in the sustainable utilization of plant resources in coastal areas. This paper has taken evaluations on the economic uses of salt-tolerant plants and given suggestions for saline soil improvement and resource utilization in coastal areas. Based on the results of investigation and experiments, we suppose that the salt-tolerant plants in coastal areas can be grouped into 9 main groups according to their economic value： pioneer plants for saline land improvement, medicine, edible and forage plants, industry material, forestation, breeding material, energy plants and eco-tourism resources.
