The practices result inthe expansion of areas affected by secondary salinization( Szabolcs １９８６) . The countermeasures to cope with the soil salinizationproblem include the utilization of salt tolerant crops or halophytes .Materials and methods The field survey was carried out during June to October , ２００３ at ５ sampling sites distributed on saltaffected areas in Middle to Western parts of Inner Mongolia ( Ejinor , Xlingol , Cagnnor ,Wlingsu and Jrndi) . The halophyticplant samples were collected from １m × １m size quadrats . The scientific names of families and species of plants were identifiedand recorded . The number of stocks , size of stocks , plant height and biomass of each species were measured .Results Plant ecological analysis was carried out around salt lakes and salt affected areas in central to western parts of InnerMongolia . Special attention was paid on the usage of plants . Halophytes of ２０ families with １１３ species were recorded on ５sites . Among them , there were ３４ medicinal plant species and ４１ forage plant species ( among them , １１ species have highquality for forage) . Twelve species were common with Japanese flora . Fif ty eight species have their close relatives in Japaneseflora . Plants with no close relatives in Japanese flora numbered ４０ in family level and ３ in species level . Chenopodiaceae plantslike Salicornia , Suaeda and K alidium formed colonies as pioneer plants on the salt affected areas in central to western parts ofInner Mongolia . Phragmites australis , Salicornia europ aea , and Suaeda corniculata produced high biomass at the centralparts of salt affected areas . The biomass of these species was ２３ .８ , ８ .９ , and ７ .２ kg /m２ , respectively . Species diversitycalculated by Simpson摧s index ranged between ０ .０００ and ０ .７９１ . On the plot where salt accumulated more , the index fellaround ０ showing the breakdown of diversity .Conclusions From the experimental results stated above , the following suggestions for the utilization of halophytes wereobtained . Halophytes such as Salicornia , Suaeda and others distribute naturally in the salt affected areas . Their biomassproduction is quite high . Selecting the proper species , animal feed can be produced . The feasibility expands the options ofcountermeasures to resume destroyed plant vegetations .This paper intends to introduce the major plant species , which distribute on the salt affected grasslands in middle and westernpart of Inner Mongolia , with their characteristics . The utilization of these species was also discussed . The associated objectiveof the paper is to provide a convenient list of plant species to assist Japanese researchers for their field studies or for theirreferences in the laboratories .ReferenceSzubolcs .I .(１９８６) .
