美洲斑潜蝇在湛江市的发生与防治

调查了潜蝇在湛江市的发生与为害情况，结果表明，美洲斑潜蝇（LiriomyzaSatiuaeBlanchard）是为害作物潜蝇的优势种，包括有6个科18种，年间发生有6个为害高峰期。应用绿潜宝、乐果、巴丹等药剂在发生为害高峰期的峰前、中、后三次用药，防治效果维持70％以上。     

新疆阿尔泰哈巴河一带古生代火山岩的形成与演化

文中详细地论述了新疆阿尔泰哈巴河一带古生代火山岩的地质、岩石化学、稀土元素地球化学特征。将其分为三个类型，认为火山岩是在陆缘裂陷槽的区域构造背景下发生和演化的。对各类型火山岩岩浆来源，上升模式也做了初步讨论。     

水准测量资料中的地形效应

本文首先用有限元方法对几种不同的地形模型进行了分析。所得的结论是:由于实际地球表面地形的起伏不平,水准测量资料与地形之间具有相关性,即水准点高程变化与该点高程之间呈相关性。最后,本文对今后水准测量资料的分析处理提出了建议。     

沂沭断裂带内部王氏组的沉积环境及构造意义

本文将晚白垩世王氏组的沉积相划分为五类:湖盆陡岸浊积扇相、洪积扇沉积相、滨—浅湖前缘斜坡相、次深湖相、湖湾相。并对其微相特征进行了详细研究。王氏组沉积特征所反映的沂沭断裂带之活动特点是:先为徐缓的脉动,而后是陡然激烈的断陷,故造成了补偿性沉积与超补偿性沉积的叠置。王氏组砂岩平均化学成分表明:马站盆地具弧后盆地性质。

Atmospheric radiative transfer simulation for atmospheric correction of remote sensing data

IntroductionThe radiance leaving the earth-atmosphere sys-tem which can be sensed by a satellite borne ra-diometer is the sum of radiation emission fromtheearth surface and each atmospheric level that aretransmittedtothe top of the atmosphere.The radia-tion emissionfromthe earthsurface andthe radianceof each atmospheric level can be separated fromtheradiance at the top the atmospheric level a satellitemeasured.Thus,the earth surface parameters willbe retrieved from the surface radiance after a…     

绿化黄河工程土地资源促进沿黄生态环境建设

1998年以来，国家加大对防洪工程建设投入的同时，也对工程环境保护和建设提出了更高的要求，防洪工程绿化建设已纳入了全国生态环境建设和城市总体规划，是生态建设和经济可持续发展的战略布置。它不仅可保持工程的完整，提高工程的防护性能，为抢险提供丰富的物料，而且绿化黄河沿岸，对改善生态环境，美化黄河景点，建立沿黄景观带，发展旅游观光业具有非常现实而且深远的意义，同时也是将黄河堤防建设成为防洪保安线、抢险交通线、生态景观线的重大举措。     

The possible response of life zones in China under global climate change

The response of natural vegetation to climate change is of global concern. In this research, an aggregated Holdridge Life Zone System was used to study the possible response of life zones in China under doubled atmospheric CO₂ concentration with the input climatic parameters at 0.5×0.5° resolution of longitude and latitude from NCAR regional climate model 2 (RegCM2) coupled with the CSIRO global climate model. The results indicate that the latitudinal distribution of life zones would become irregular because of the complicated climate change. In particular, new life zones, such as subtropical desert (SD), tropical desert (TDE) and tropical thorn woodland (TTW), would appear. Subtropical evergreen broadleaved forest (SEBF), tropical rainforest and monsoon forest (TRF), SD, TDE and TTW zones would appear in the northeastern China. Cool-temperate mixed coniferous and broadleaved forest (CMC) and warm-temperate deciduous broadleaved forest (WDBF) zones would appear at latitudes 25–35°N. The temperate desert (TD) in the western China would become Tibetan high-cold plateau (THP), SEBF, WDBF and temperate steppe (TS), and a large part of THP would be replaced by TRF, TDE, SEBF, TS and TTW. The relative area (distribution area/total terrestrial area) of CMC, TRF, TDE and TTW zone would increase about 3%, 21%, 3% and 6%, respectively. However, the relative area of SEBF, TS, TD and THP would decrease about 5%, 3%, 19% and 4%, respectively. In all, the relative area of forests (CCF, CMC, WDBF, SEBF, TRF) would increase about 15%, but the relative area of desert (TD, SD, TDE, and TTW) and THP would decrease about 9% and 4%, respectively. Therefore, responses of different life zones in China to climate change would be dramatic, and nationwide corridors should be considered for the conservation of migrating species under climate change.
