Dear Editor,Deep burrowing and soil surface feeding earthworms,so-called strict-anecic and epi-anecic species(Hoeffner et al.,2019),are a highly influential soil faunal group in many natural and manmade ***,they are relatively large and contribute substantially to the formation and processes of mull-type soils through effective foraging and incorporation of plant litter(Edwards and Bohlen,1996).The wide,vertical,and deep burrows of anecic earthworms produce a unique influence on soil physical properties(lamparski,1985;Shipitalo and Butt,1999;Nuutinen et al.,2001).Lumbricus badensis(Michaelsen 1907)is an intriguing example of this type of earthworm.

Land Use Change and Anthropogenic Driving Forces:A Case Study in Yanhe River Basin

Human activities alter land use patterns and affect landscape sustainability. It is therefore very important to investigate the relationship between land use change and human activities. This study focuses on the detection of changing land use patterns in the Yanhe River Basin in northern Loess Plateau of China between 1995 and 2008. Landscape metrics were used to analyze the changing land use patterns and to explore the related anthropogenic driving forces. Results show that:1) Totally, 186 590 ha of croplands were converted into alternate land-use types (equivalent to 61.7% of the original cropland area). The majority of cropland areas were found to be converted into grassland and woodland areas (accounting for 55.9% and 4.9% respectively of the original cropland areas). 2) Both cropland and woodland demonstrated an increasing fragmentation tendency while grasslands showed a decreasing fragmentation tendency. 3) Multiple driving forces of land use change were thought to act together to changes in landscape metrics in the Yanhe River Basin. The anthropogenic driving forces were analyzed from four perspectives:ecological conservation policy, labor force transfer, industrial development, and rural settlement. The policy of the GfG (Grain for Green) project was the main driving factor which expedited the conversion from cropland to woodland and grassland. Industrial development was also found to affect land use change through the direct impact of economic activities such as oil exploration and agricultural production, or through indirect impacts such as the industrial structures readjustment. Labor force transfer from rural to urban areas was found to follow the industrial structure readjustment and further drove land use change from cropland to off-farm land use. Establishment of new tile-roofed houses instead of cave-type dwellings in rural settlements has helped to aggregate the original scattered land-use type of construction.

[目的]调查患有或不患有氯痤疮的三氯苯酚(tri-chlorophenol,TCP)或五氯苯酚(pentachlorophenol,PCP)接触工人血清的二恶英水平,并观察患氯痤疮工人的特征。[方法]收集26名PCP工人、12名TCP工人和36名没有PCP和TCP暴露史工人的血样,并测定二恶英含量。氯痤疮的确定根据工厂医疗记录。[结果]PCP工人中,患氯痤疮与未患氯痤疮的工人相比具有更高毒性当量(根据世界卫生组织)的2378-TCDD,12378-PeCDD,123678-H6CDD,123789-H6CDD和123678-H6CDF水平。而在TCP工人中,虽然曾患有氯痤疮的工人血清中2378-TCDD水平较高,但与未患有氯痤疮者的血清水平上并无明显差异。氯痤疮的公认危险因素有首次暴露年龄较小和距第一次暴露的时间较长等,但仅在接触TPC工人中得到证实。PCP工人患氯痤疮和诊断前较长的接触时间相关。[结论]氯痤疮是二恶英高暴露的良好指标。TCP和PCP接触工人的血清二恶英同系物具有明显不同的特点。
