广东阳江沿海地区海陆风观测结果及其特征分析

根据我国广东阳江某大型电力工程项目前期工作中获取的气象资料，分析了该地区海陆风环流特征。结果表明该地区海陆风频率较高，但相当一部分环流较浅（尤其是春季）；海风持续时间平均为9－10小时；白天的海风比夜间的陆风要强得多，高空回流层的气流强度远小于地面入流层的强度；海陆风环流结构比较特殊，其上下层风向间以及白天的海风风向和晚上的陆风风向间大多有较大夹角，不易形成重复污染。

The Correlation of Inorganic C,O Isotopic Values for Lake Chenghai Sediments and Its Environmental Implications

As one of the lakes on the Yunnan-Guizhou plateau, Lake Chenghai, which is a typical closed lake with the precipitation accounting for one-third or more of the annual water input, has a high total salinity (almost like a saline lake). The inorganic C, O isotopic composition of lake sediments bears much sensitive information about environmental change in the catchment, while their correlations revealed the hydrological conditions under which the lake was closed. Their compositional variations are controlled by temperature, precipitation, photosynthesis, dissolving equilibrium of the carbonate system and hydrological condition. According to our research on inorganic C, O isotopic composition of Lake Chenghai sediments, we investigated the environmental change of this catchment several decades ago. The results showed that Lake Chenghai has kept good hydrological closing conditions in the past several decades, as indicated by the good correlation of inorganic C, O isotopic composition of sediments; and that the environmental change in this catchment shows a tendency of periodical evolution on a 10⁻¹¹-years scale, although the signal noise is relatively high at the bottom of the sediment core. And we also can extend C, O isotopes, a sensitive environmental indicator, to nearly saline lake environments with a high degree of mineralization.

应用卫星多角度遥感识别被老鼠和昆虫破坏的草地(英文)

该文研究用ＡＶＨＲＲ数据监测Ｒｕｏｒｇａｉ县大草原被老鼠、昆虫破坏的情况。鼠虫危害区的光谱特征是：ＡＶＨＲＲ数据的可见光波段（０．５８－０．６８μｍ）地面反射率（ＣＨ１）较高，近红外波段（０．７２５－１．１μｍ）的地面反射率（ＣＨ２）较低，红外辐射波段（３．５５－３．９３μｍ）的亮度温度（ＣＨ３）较高；鼠虫危害区的遥感信息特征在雨季７月最为明显；可用比值植被指数ＲＶＩ（ＣＨ２／ＣＨ１）确定鼠虫危害程度；用多角度获得的ＲＶＩ可反映鼠虫危害。结果显示在这方面上，多角度遥感比多波段光谱法能更好地识别老鼠、昆虫破坏的地区。
