The result pointed out that the vertical distribution of foliage for each species was different,however,generally speaking,the foliage in upper crown (0.3CL) for broad-leaved species in natural secondary forest took a small percentage,about 10%;in middle or middle lower of the crown(0.4CL to 0.8CL) the branches here took the majority percentage of whole foliage,almost 60%to 75%;but in lower crown(0.8CL),there was about 10%of whole foliage.(5)The interspecies competition of trees in secondary forest was expressed by Hegyi competitioin index,and the active competitor was calculated by the competition zone radius and the tree position,DBH,and distance in the zone,it was not all competitors in tranditional calculation.The study introduced crown area overlap index to describe the crown competition between subject tree and its competitors,furthermore,the crown area was classified into 5 levels with a method of equal crown projection area,therefor,the resulting crown area overlap index showed more realities of existing stand conditons.(6)Based on the theoretics of multiply divide,the spatial strcture optimizing model of secondary forest stand selective thinning was developed by diversity mingling,aggregation index,competition index and crown area overlap index,also designed 10 constraint conditions which were related to forestry meanings,the objective function was solved by the implicit enumeration method with LINGO 9.0,using 0-1 integer programming.

并且得出，每个树种在树冠内相对高度上的叶量的垂直分布是不同的，天然次生林阔叶树种的叶量在树冠的上部(0.3CL以下)所占比例很小，约占10%左右；在树冠的中部以及中下部(0.4CL～0.8CL)，叶量所占比例最大，几乎集中了整个树冠60%～75%的叶量；而在树冠的下部(0.8CL以下)，几乎占很少的叶量，大约10%左右。5、采用Hegyi竞争指数来表现次生林内林木的竞争关系，并且根据竞争圈的大小和林木在竞争圈内的分布位置、大小与距离来计算有效的竞争木，并不是传统意义上的全部竞争木；本研究提出用树冠叠加指数来表示林木与周围树木的树冠竞争情况，并采用等树冠投影面积法把树冠分为5级，这样计算的树冠叠加指数更加与现实林分相符。6、本研究基于乘除法的思想，用多样性混交度、聚集指数、竞争指数和树冠叠加指数构建了天然次生林择伐空间优化模型，设计了10个与林学意义相一致的约束条件，并采用0-1整数规划的思路，在LINGO9.0软件中使用了隐枚举法对目标函数求得最优解。7、以M702标准地为应用实例，具体计算出了每株采伐木，经过择伐后，目标函数值按模型设计的要求发生了极大的改变，增加了5倍多，说明了最后这个解的优良性，满足了设计的要求。

Pure-remote sensing information models are free of the numerous distributional parameters that are difficult to obtain in vast area. The following sections are included in the study.(1) The VCI and SVI based on time-series NDVI data are used to analyse regional drought and the following results were reached: As the vegetation growth status index, the response of VCI and SVI to precipitation was land cover type, temporal and site specified. So VCI and SVI have little information about drought when used to monitor regional drought especially in China that has a mountainous topographty.(2) Based on the interpretation of NDVI-Ts space, NDVI and land surface temperature was combined to construct NVDI-Ts space from which the TVDI (Temperature Vegetation Dryness Index) was obtained with line ratio method and normalized slopes method. When compared with the topsoil moisture measured in situ, TVDI are competent in regional drought monitoring. Illumed by the NDVI-Ts space, we combined the NDVI with day/night land surface temperature difference and apparent thermal inertia to construct NDVI-ΔT and NDVI-ATI spaces from which the DVDI and AVDI were estimated respectively with 8-day composite MODIS 〓 product and 16-day composite MODIS NDVI product.

具体包括以下几方面的内容：(1)VCI和SVI在干旱监测中的作用评价：探讨利用NDVI时间系列数据建立的植被状态指数和标准植被指数评价区域干旱的可行性，研究结果表明：VCI和SVI作为植被相对生长状况指标，对降水的响应随着植被覆盖类型、时间和空间等而表现出不同的敏感性，因此在大区域干旱监测中，特别是我国这样地形复杂多样的国家，VCI和SVI在干旱监测中的作用都是有限的；(2)利用TVDI评价全国干旱等级分布：结合陆地表面温度和植被指数建立NDVI-T〓空间，在NDVI-T〓空间物理意义理解的基础上，分别采用线段比值法和斜率归一化法构建温度植被干旱指数，并利用TVDI研究了我国2000年3～5月份各旬的干旱分布，取得比较满意的结果。
