By using the normalized difference vegetation index extracted from CBERS-02 data and the leaf area index data obtained from field measurement, this paper analyzed the relationships between the NDVI and the LAI of total samples of meadow, marsh vegetation, shrubs, and islanded forests of the wetland vegetation in Honghe Nature Reserve of Sanjiang Plain. The linear and non-linear regression models between NDVI and LAI of different wetland vegetation types were established, and the spatial distribution of LAI in the Honghe Nature Reserve was mapped.

Based on detailed geological observation and precise dating of porphyries in combination with data available, the authors hold that the Indosinian porphyries in the Zhongdian island arc zone can be divided into two parts, i.e., the eastern porphyry belt formed during 218～203 Ma and the western porphyry belt formed during 242.92～237.5 Ma.

In this his dissertation, the field geological work and modern analysis were finished on the Qulong ore-bearing porphyries. The mineralization chronology, petrology, element and isotopic geochemistry were studied on the porphyries. This dissertation also compare this work in Qulong ore-bearing porphyries with other ore-bearing porphyries in Gangdese belt, in order to probe into dynamical background and mineralization features of the ore belts in the condition of India-Eurasia collision.

Methods The net treated by BASF pesticide, the net treated by BASF pesticide after washing twenty times and the net treated by Fendona TM recommended by WHO were used in treated area, and common military nets were selected in the control areas. Aedes vexans, the dominant species in Beiwan, was collected by mosquito aspirators and released into nets. The first knockdown time, medium knockdown time and total knockdown time were recorded, and then compare the knockdown time of 4 kinds of mosquito-net.

Interlayer oxidized zone can be divided accurately by Fe_2O_3, Fe_2O_3/FeO and U parameters. We can correct the field macroscopic color zoning by combining the macroscopic zoning and microscopic zoning. Univalent major elements components(Al_2O_3, SiO_2, K_2O, Na_2O) show remarkable activity at the process of interlayer oxidizing, their contents are variable and mingled in different zones and it can't be used in zoning. But we can speculate the developmental degree of interlayer oxidized zone and uranium mineralization according to the concentration trends and variation characteristics of sensitivity group, activity group and their ratios .(3)The comparatively steady elements such as lithiphile elements, sulfophile elements and high field strength elements change regularly at the process of interlayer oxidation except some radioactive elements. Trace elements and rare earth elements commonly enrich in thin rock clast such as mudstone, in which the enriched elements species are more than those in the whole rock, which indicate that the regeneration action in caulking matter are more deep than that in whole rock at the process of interlayer oxidation, and the reallocate intention of trace elements in main minerlized rock in Tuha basin are more intensive than that in Yili basin at the process of deposition ,diagenesis and later changes .
