受到钱理群&单位意象&研究方法的启示，首先以学界的几种观念界定散文诗的文体特征，接着从现代散文诗的引进背景谈起，在梳理《野草》的生成中，注意到《自言自语》是其创作来源的事实，于是串接两者在主题内容上的联系，分析演变的内在根据。

Experiments of bioremediation and control were conducted with the alkali meadow grass planted in saline soil for 3 years. Contrasted with control group, topsoil desalination rate was up to 77.00%; pH value decreased 0.25 pH unit; soil bulk density decreased 0.14 g/m^3; total porosity increased by 5.29%; soil aggregate structure increased by 23.14%; soil water content increased 70.30 g/kg; average triennial alkali grass yield was 36000 kg/hm^2. In addition, planting forage in saline soil as a medium and establishing a compound agro-forestry-animal system promoted the sound combination of planting industry, forestry, and livestock husbandry. Because of the reasons, utilization ratio of land reached more than 184.00%; the income of land increased from 16300 to 35500 yuan/hm^2 average income per farmer in the controlling region increased by 66.00%, from 2160.70 to 1300.80 yuan.

生物修复与调控试验研究表明，草甸盐土经种植碱茅草3a，耕层土壤与对照相比脱盐率达77.00%，pH值下降了0.25个单位，容重降低0.14g/立方公尺，总孔隙度增加5.29%，团粒结构增加了23.14%，自然含水量增加70.30g/kg.3年生碱茅草平均产草量36000 kg/hm^2；盐化耕地采用以种植牧草为中介，将种植业与农区林业、畜牧业有机结合成互相依存，互相促进的农林牧复合生物系统治理后，土地利用率可达184.00%以上，可获得16300~35500元／hm^2的经济收入，治理区农户人均纯收入由1300.80元增加到2160.70元，增加了66.00%。
