Based on crisis management for the important transition zones of nature reserves,the protection agreement mechanism is introduced to solve management deficiencies for the important transition zones of nature reserves. The results indicate that the agreement protection mechanism will be handed over to the community and farmers,which will encourage the communities and social organizations to participate in conservation.The protection mechanism can effectively alleviate the transition zone biodiversity crisis,maintain ecosystem integrity and security of the core area and the experimental area and address such the main problems as the absence of nature reserve management system and management deficiency.

Based on the field investigation data,the post-fire forest regeneration and fuel load in Platycladus orientalis forest、Pinus tablaeformisforest forest、Robinia pseudoacacia forest and Fraxinus chinensis forest were studied in Beijing Xianshan Forest Farm.In which,the first two forests was burned in 2003 and the other two stands burned in 2006,also,the artificial regeneration mode was used in the first forest and the natural regeneration mode was used in other three stands,and the potential combustibility of regeneration forests was discussed.The results showed that the post-fire biodiversity index decreased,but the total fuel load increased in the Platycladus orientalis forest compared with the unburned site;on the contrary,the biodiversity index increased,and the total fuel load decreased in the other three forest types compared with the unburned sites.The accumulation of post-fire fuel load indicated the positive relation with the regeneration time;also,the flammable fuel load increased after burning,thus the potential combustibility is increased in the post-fire forest.

As an endemic to China,Juglans mandshurica is one of the rare and endangered plants under protection in Shanxi Province.The individuals of species is shrinking due to serious impacts by human activities,so it is important to study the relationship between J.mandshurica and its habitats for scientific protection.Based on niche theory,niche width and niche overlap of 26 dominant species in J.mandshurica communities in Lishan Nature Reserve of Shanxi were analyzed.The results demonstrated that the constructive species and dominant species,such as J.mandshurica,Forsythia suspense,and Carex lanceolata had a broad niche,because they were widely distributed with more individuals,and had stronger competition for resources.Other species such as Toxicodendron vernicifluum and Rhamnus parvifolia had narrow niche width.The results of general overlap showed that 26 dominant species were not of completely general overlap.The species with wider niche width had wider niche specific overlapping with the other species,such as J.mandshurica,Forsythia suspense,Syringa pekinensis with other species.But some species pairs with wider niche width had narrow niche specific overlap,such as J.mandshurica and Ajuga ciliate,Syringa pekinensis and Artemisia subdigitata etc.The species with narrower niche width are likely to have higher niche specific overlap such as Ostryopsis davidiana and Crataegus pinnatifida.

The Vatica mangachapoi forest in Shimei Bay has an important role of natural model in rehabilitation and reconstruction of coastal shelterbelt.The characteristics of community structure and natural regeneration in Shimei Bay Vatica mangachapoi forest were investigated and analyzed by using plot survey method and the results showed:overcut forest and secondary forest have obvious different features,in which the basal area and average DBH of the Vatica mangachapoi in the overcut forest were 53.98% and 19.43% higher than those in the secondary forest,but the density of the Vatica mangachapoi in the secondary forest was 17.47% higher than that in the overcut forest.The Vatica mangachapoi was the predominant species in the two kinds of forest stands,with over 95% of Vatica mangachapoi composition (basal area) and over 0.8 of the importance value.The diameter structure of Vatica mangachapoi was mainly distributed among 5～20cm diameter classes,in which most of trees are in 5～10cm diameter classes,with 74.6% and 66.1% of the total numbers separately in secondary forest and overcut forest.The natural regeneration numbers of the Vatica mangachapoi saplings in the two kinds of stands were adequate,but the numbers of seedlings in the overcut forest were inadequate,with only 1550 trees per hectare.The regeneration seedlings and saplings fit aggregated distribution,with a very high degree of aggregation.

Based on the forest resource inventory data,according to the relationship model between sub-compartment volume and forest biomass,the forest biomass of 301 Forest Farm in Miyaluo forest region of west Sichun province was estimated.The forest biomass under each age class was analyzed,as well as the biomass of different forest type.The results indicated that the total biomass of the studied area was 3 041 229t,the average biomass was 87.13t/hm²,which is less than the average value of biomass both in national and Sichuan provincial level. This is mainly caused by poor quality of the site in which the main dominant species(Picea balfouriana and Abies squamata) are located,and caused by the low biomass value. The age structure of main forest type is irrational and the biomass from mature and over mature forest accounts for 69%.Among different forest types,the soil and water conservation forest occupied 80% of the total biomass.This study provided scientific basis for the forest resources management in the studied area.

This paper studies the regeneration density of different types of forest gaps,the number and causes of the edge of wood.The results showed that gaps are generally formed by 11 to 24 larch and birch trees with an average number of 16.94 trees, which includes standing dead trees, broken trees and uprooted trees. Of those trees, 11.8% are broken trees, 353% dead standing trees and 41.2% uprooted trees. Gap where the slope was lower in 58.9% and slope position,41.1% were in the upper slope.Ledum leaves in the forest,grass and moss larch forest regeneration density by the limiting factors are different.In the larch forest Ledum gap regeneration is mainly affected by the impact of slope,grass leaf pines,mainly by the length of the gap regeneration of the axis ratio,moss larch forest gap edges of wood mainly by the number of edge trees.

Taking Linze county as a study area,using GIS technology,based on the administrative division, the natural and geographical conditions,this paper plots out the evaluation unit of land in Linze county,filtrates the evaluating index by applying Delphi method,establishes the evaluation index system and determines the weight value. Then we calculate comprehensive assessment value with SAW method and set up the grade standard of suitability about land ecosystem. On the basis of the grade standard determination,we divide the sub-areas of adaptability of land ecosystem in Linze county,identify the usage of each sub-area,finally sets up the proper mode to adapt to eco-development. This provides scientific basis for development of ecological security barrier in the county.

There are three distinct mechanisms to compensate unavoidable wetland impacts in USA to satisfy the requirements of rules in order to reach the government’s wetlands “no net loss” goal.Permittee-responsible mitigation,mitigation banking and in-lieu fee mitigation are the three mechanisms.Federal regulations in USA establish a flexible preference for using credits from a mitigation bank over the other compensation mechanisms,which are growing fast in the past 30 years.The wetlands compensation system in USA can give our country great reference for wetland protection,which includes the idea of compensation,using market instrument for protection of wetlands and effective government management mechanism.
