【摘要】 广西植被生境的主要特点是地形复杂,山多平原少,土壤类型多样,气候高温多雨,降雨时间集中,水土流失和土壤贫瘠化严重。植物区系具有热带向亚热带过渡的性质,有不少的优势品种。根据广西主要粮经植物的分布概况,以及农业生产环境中的生态学问题进行讨论,并对如何开发利用振兴广西提出3点建议:1)保护和发展生态林业,根治环境恶化;2)因地制宜充分利用植物资源,建立土特产基地;3)旱地耕作推行混农林业,增加植被覆盖率,提高光、热、水、土资源的利用率。更多还原

【Abstract】 The chief characteristics of habitats of the vegetation in Guangxi province include : complex topography, much larger proportion of mountain area than plain area, diversification of soil type and climate with abundant quantity of heat and rainfall. As a result of abundant rainfall occurring in a relative short time within a year and the complex topography, the soil erosion and infertility are serious in the agriculture ecosystem in Guangxi. Guangxi flora possesses characteristics of transition from tropical flora to subtropical flora. There is seme dominant species in Guangxi. This paper also states briefly the distribution of main crops and economic plants and indicates the ecological problems of agricultural ecosystem in Guangxi. Based on the results above, the paper puts forward three strategical ways to deal with the problems of agricultural macro-designing programme. They are; 1. Protect and develop Ecological Forest so as to eradicate the deterioration of the agricultural environments. 2. Utilize the plant resources in line with local conditions and establish product bases for special native economic plants. 3. In nonirrigated farmland tillage, agroforestry should be carried out so that the rate of vegetation covering can be increased. And in this way, the utilization rate of resources of light, heat ,water and soil can be also enhanced greatly with the arrangement of various plants and domestic animals in the ecosystem.更多还原
