滇池流域典型小流域农业种植情况调查

采用资料收集、GPS定位、实地踏勘及走访式问卷调查方式,对滇池流域典型小流域柴河流域、牧羊河流域、宝象河流域的农业种植基本情况进行抽样调查,调查结果显示小流域上游到下游,农民人均耕地面积不断减少,复种指数和大棚种植比例逐渐增加;柴河流域的化肥施用强度上游高下游低,宝象河和牧羊河流域的化肥施用强度上游低、下游高。

A Survey on Agricultural Cultivation in the Typical River Basins of Dianchi Lake Catchment

The sampling investigation has been conducted in the small typical river basins of Dianchi Lake catchment, namely Chai River Basin, Muyang River Basin and Baoxiang River Basin, on the basic situation of the agri, cultural cultivation. The methods applied in the survey include data collection, GPS positioning, field visit, interviews and questionnaire survey. The results show that from the upstream to the downstream of these small watersheds, the per capita arable land is declining, while the multiple cropping indexes and the proportion of greenhouse cultivation are increasing. In Chai River Basin, the intensity of fertilizer application in the upstream is higher than its downstream. It is just an opposite case for Baoxiang and Muyang River Basins.
