The area ratios of 980/1022, 980/1047,(980+1047)/1022 and 980/(1022+1047) cm^(-1) were decreased as the degree of acetification increased which indicated that acetification induced a decrease of crystallinity of starch. And the crystal structure changed from A-type to V-type. For the cross-linking of POCl3, the area ratios of 980/1022, 980/1047,(980+1047)/1022 and 980/(1022+1047) cm^(-1) were also decreased as the degree of cross-linking but the decrease was little compared to that of acetification. The result indicated that cross-linking of POCl3 had little effect on the starch crystal structure.

随着醋酸酯化取代度的增大，980/1022、980/1047、(980+1047)/1022和980/(1022+1047)的相对峰面积的比值均呈现下降趋势，表明醋酸酯化改性会导致淀粉结晶程度降低，结晶形态从A型转变为V型；随着交联度的增大，980/1022、980/1047、(980+1047)/1022和980/(1022+1047)的相对峰面积比值均呈现下降趋势，但下降程度较小，表明三氯氧磷交联对淀粉结晶结构影响不明显。

For the leaf area index of the three forest types, there was a similar variation trend, i.e ., increased first and decreased then, with the maximum presented in mid-July or August for Q. mongolica and J.mandshurica forests while in mid-August or September for F. rhynchophulla forest. The canopy porosity of the three forest types also had a similar variation trend, but opposite to leaf area index, being decreased first and increased then, with the minimum presented in mid-June, July, August or September. The analysis of variation coefficients of leaf area index, transmitted direct gap light, and transmitted diffuse gap light indicated that the spatial pattern of leaf area index in July-September was the main factor affecting the spatial distribution of transmitted diffuse gap light.

结果表明，3种林型的叶面积指数变化总体趋势是一致的，均呈先上升再下降的单峰曲线，蒙古栎林和胡桃楸林都是在7月中旬或8月中旬达到最大峰值，花曲柳林是在8月中旬或9月中旬达到最大峰值；3种林型冠层孔隙度的变化总体趋势也是一致的，呈先下降再上升的单峰曲线，不同样地峰值出现的时间也不同，最低峰值在6、7、8、9月中旬均有出现；通过对不同月份的叶面积指数、林下散射光、林下直射光的变异系数分析表明，7—9月叶面积指数的空间格局是影响林下散射光空间分布的主要因素。

The submodel quantitatively characterized the impact of genotypic differences on sowing date and sowing rate by tillering ability and percentage of final spikes to effective tillers, and the suitable pre-winter leaf number on main stem in relation to yield target is quantified according to the principle of determining spike number from yield level and leaf number from spike number.

其中，播前方案设计的知识模型包括产量目标，品种选择，播期确定，基本苗及播种量的计算，氮、磷、钾肥料运筹和水分管理；动态调控指标的知识模型包括适宜生育期，穗分化进程，群体茎蘖动态、叶龄动态、叶面积指数动态和干物质积累动态等生长指标动态以及有效叶面积率、高效叶面积率和粒叶比等源库指标。

Second, wetland landscape pattern dynamic change of Kenli County Take TM as the information source, according to studies the region wetland ecosystem present situation characteristic, wetland is divided into 10 kinds: irrigation paddy field, pit pond water surface, cultivation water surface, artificial ditch, reservoir water surface, salt field, rivers water surface, reed, shallow seas and tidelands, beach. The wetland landscape area is remarkable dropt from 1987 to 2004.In 1987 the wetland area occupied 14.10% of Kenli county, but only was 12.33% in 2004, it reduced 6155.12 hm2 in 17 years and average reduced 362.07 hm2 every year, the reduction scope of shallow seas and tidelands wetland is biggest 3894.78 hm2. The shallow seas and tidelands and reed are frequent transformation with other type.

2查清了研究区湿地景观格局动态变化规律以TM影像为信息源，根据研究区域湿地生态系统现状特征，把垦利县湿地分为10类；湿地景观面积在研究时段内呈显著下降趋势，1987年湿地面积占整个研究区总面积的14.10%，但到2004年只占12.33%，17年共减少6155.12 hm2，平均每年减少362.07 hm2，其中滩涂湿地面积减少幅度最大3894.78 hm2；从各湿地类型之间的转换来看，各种湿地景观之间、湿地和非湿地之间相互转化和逆转并存，滩涂和苇地与其他地类转换频繁；研究区湿地景观斑块数量增多，景观多样性指数1987年为1.7643，2004年下降到1.7105，均匀度指数由1987年的0.6873上升到2004年的0.6923。

Haifeng County, Luhe County, hosted Lufeng and a Red Bay Development and the Overseas Chinese Economic Zone Management Area, are Under the jurisdiction of city, which is with a total population of 3.23 million, urban population of 210,000, living abroad overseas Chinese, Hong Kong Macao and Taiwan compatriots, a total of more than 130 million people; total land area of 5271 square kilometers, accounting for 2.93% total area of the province, of which 93.2 thousand hectares of cultivated land, garden 42.1 thousand hectares, woodland 234.8 thousand hectares, unused land 47.9 thousand hectares; a coastline of 455 kilometers, sea area of 23.8 thousand square kilometers, accounting for the province's land area 14% of the ocean, in which shallow seas and tidelands 69.6 thousand hectares.

下辖市城区、海丰县、陆河县，代管陆丰市，并设有红海湾开发区和华侨管理区两个市辖经济区，总人口323万，市区人口21万，旅居海外华侨、港澳台同胞共有130多万人；陆地总面积5271平方公里，占全省总面积2.93％，其中耕地面积9.32万公顷，园地4.21万公顷，林地23.48万公顷，未利用地4.79万公顷；海岸线长455公里，海洋面积2.38万平方公里，占全省海洋国土面积的14%，其中浅海、滩涂6.96万公顷。

The strongly negative correlation between winter sea-ice extent of Davis Strait and August rainfall of North China turns into bad correlation.

冬季戴维斯海峡海冰面积和北半球夏季、7月500Hpa位势高度场年际关系的年代际变化主要是相关系数分布型的变化：1974年前，相关系数分布型呈一个自新地岛开始经巴尔喀什湖到日本海的&-+-&型，该型和同期华北降水的反相关较好；1974年后，相关系数分布型变为呈自乌拉尔山开始经贝加尔湖到河套的&+-&型，该型和同期华北降水相关差。1974年前，冬季戴维斯海峡海冰面积和北半球8月500Hpa位势高度场的相关系数呈一个自乌拉尔山开始到鄂霍次克海以北分布的&+-+&型，该型和8月华北降水的反相关较好；1974年后，相关在欧亚大陆地区变差，没有明显的相关型，冬季戴维斯海峡海冰面积和8月华北降水关系变差。
