DOC and HDOC in ridge, rice and rape use pattern in 0~30cm depth layer much more than other treatments after 14 years and showed significant differences;land use of rotation of waterlog rice and dry rape which was disadvantageous to increase the quantity of DOC, which indicated DOC is good evaluation index of soil quality land use effect for paddy soil.

土壤有机质损失的重要途径主要是DOC的淋失，土壤可溶性有机碳是土壤有机碳周转的必要环节，是其中的不稳定组分，主要包括有机残体的可溶性有机物、土壤微生物分解有机残体后未吸收的可溶性有机物及微生物细胞衰老自溶后释放的可溶性有机物[4]，在陆地生态系统碳循环中起着重要作用[5]，所以DOC的分析

Supervised and unsupervised image classification were applied to the study area TM image and t o the paddy field TM image. And the early rice areas were calculated by each met hod. Using the proposed methodology improved the quantitative accuracy of ear ly rice area estimated up to 93.98%, whereas it was 82.83%when image classific ation was used only. The extracted information from the c lassification is belonging to the early rice and not to any other vegetation. Si nce the GIS database is available, the method is easily applicable to any new RS images.

不同方法比较结果表明：非监督分类法不能用于提取丘陵山区的水稻种植面积；只用TM资料估算龙游县早稻面积，与统计数据相比，平行六面体分类法、最大似然分类法精度分别达到82.83%和59.95%；而用GIS 与TM资料集成技术对水田分布图进行分类估算早稻面积，平行六面体分类法、最大似然分类法的估算精度分别达到93.98%和60.65%，所以利用平行六面体分类法对南方丘陵山地早稻种植面积估算是可行的。

The comparison of pollen contents inside and outside the rice field and in the dust indicates that the Poaceae pollen content of 36％ or higher is much likely related to rice cultivation development,even if human activities have strong impacts on the double-crop paddy areas.

稻田内外样品和尘土花粉结果的对比分析表明，在人类强烈干扰的双季稻耕作区，禾本科含量达到36％以上时，很可能表明与稻作农业发展有关。

Shannon-Wiener diversity index, Simpson diversity index and evenness index all show similar trend of change. The diversity indexes and evenness index of zoobenthos in rice-duck farming ecosystems are higher than those in normal paddy during the early stage of rice growth, but are in the reverse trend during the later stage.

水稻各生育时期常规稻田和稻鸭共作稻田底栖动物的Shannon-Wiener多样性指数、Simpson多样性指数和Pielou均匀度指数变化趋势相似，均为水稻生育前期稻鸭共作稻田的生物多样性指数和均匀度指数高于常规稻田，而后期低于常规稻田。

The results showed that the rate of mating disruption was 71.1%-80.7% caused by 150-750 rubber pheromone dispersers per hm 2. The egg numbers were reduced by 79.4%-86.1%, 72.9%-84.7%, 58.3%-65.1% and 58 9% at the treatments of 750, 300-375, 120-150 and 30 rubber dispersers per hm 2, respectively. In large scale disruption demonstrations, numbers of egg masses decreased 82.4% and 73.2% at placements of 60 dispersers per hm 2 in mid season rice seeding paddy and in early season transplanting paddy, respectively.

结果表明，田间放置诱芯150～750个/hm2的迷向率为71.1%～80.7%；每公顷放置诱芯750、300～375、120～150个和 30个的迷向区卵量比对照区分别下降79.4%～86.1%、72.9%～84.7%、58.3%～65.1%和58.9%；每公顷放置60个诱芯的大面积迷向示范区中稻秧田和早稻大田卵块量分别比对照下降 82.4%和73.2%，早稻大田枯鞘丛率比对照下降70.4%。

Rice production and sustainable development for agriculture in China waslimited by poor quality of gleyed paddy soils, such as the accumulation of reductivesubstance, low availability of soil nutrients and declined soil productivity, due to poordrainage. In the past, researches focused more on engineering technology to improvegleyed paddy soils.

潜育性稻田由于其排水不畅，造成稻田土壤通气不良、还原性有毒物质累积、养分有效化过程受阻以及土壤生产力下降等一系列问题，严重影响我国的水稻高产稳产和农业可持续发展，过去的研究仅局限于工程措施改良潜育性稻田，对施肥等农艺措施研究不够。

The effect of lead treatment on the soil microbial biomass carbon, microbial biomass nitrogen, micro-bial activities, rice physiological indices and rice biomass in the interactive system of soil-rice-lead and microbe, were studied by a greenhouse pot experiment. Lead was applied at six different levels in two different paddy soils, namely 0, 100, 300, 500, 700 and 900 mgkg^(-1) soil.

盆栽试验研究了土壤－水稻－铅－微生物相互作用的体系中，外源铅不同处理水平CK、100、300、500、700、900mgkg^(-1对两种水稻土壤微生物生物量碳、氮，微生物活性，水稻生理指标及生物量的影响。
