为了配合卧龙沙湾气象观测，探讨当地的辐射气候特征，笔者等于1983年9月上、中旬在这里进行了一次辐射气候观测，观测项目包括直接辐射、散射和地表反射率等。观测所得的数据可供了解当地气候条件的一些特点，对进一步研究当地气候状况也具有一定的价值。本文是对这次观测情况的初步分析。

The test site with a topographic shade is located in Shawan Valley, Wolong district, and the area belongs to subtropical moist zone. The observation items include:1, diurnal variation of total radiation;  2, diurnal quantity of total radiation; 3, direct radiation and indirect radiation, The related data collected is analized for the local radiation situation.

The following conclusion has been drawn from the study:

1. Though the total raiation is to a great extent impacted on by local topographical shade, the cloudy and foggy weather is a bigger factor impacting on the local sun radiation.

2. The total radiation quantity reaching the gyound is closely related to the diurnal mean temperature of earth.

3. The comparison of the test site with its surrounding meterological stations shows that the higher the altitude, the greater is its total radiation received, enven though the increase is not directly proportional.
