昆明市东郊草地资源的调查研究

INVESTIGATION AND STUDY ON GRASSLAND RESOURCES IN EASTERN SUBURBS OF KUNMING,YUNNAN PROVINCE

对昆明市东郊草地的生态条件、植物种类、植被类型、演潜规律以及开发利用进行了调查研究。该草地位处北亚热带至暖温带的过渡气候带,冬暖夏凉、雨量充沛。因此植物种类繁多,在450平方公里内,仅种子植物就多达148科,596属、1014种;适于畜牧业利用的植物群落有9个,饲用植物禾草280种,豆科牧草153种。本项草地宜与本地区农、林、果树相结合以建立生态农业草地。

The paper is an investigation and study on the ecological condition,plant species,vegetational type, law of succession and rational utilization of a certain land where it is located on a transitive climatic zone from subtropical to temperate,showing warm in winter and cool in summer with an abundant rainfall. Therefore,the amount of higher plant species is very rich.There are seed plants of 148 families,596 gene- ra and 1014 species(including subspecies,vatieties and forms)in an area of 450 km^2 solely.And 9 phyto —communities are enumerated to be suitable for use in the development of local animal raising industries, where 280 species of grasses and 153 species of legumes are good forage plants belonging to Gramineae and Leguminosae.In short,we should combine this local type of grassland production together with agriculture, forestry and pomiculture in order that we might set up and eco—agricultural system in this suburban area of Kunming for further researches from now on.
